Even if the impedance of the recording medium is to be detected as the thickness changes, the conventional electronic photographing apparatus does not have a means that can determine the timing of detecting the impedance. An object of the present invention is to provide an electrophotographic apparatus and a control method thereof for a transfer apparatus capable of constantly maintaining a high transfer performance even when the thickness of a recording material changes during recording.

In the dark place, the charging device 1 uniformly charges the surface of the photosensitive drum 6. Next, the exposure device 2 irradiates light to the corresponding recorded portrait to form an electrostatic latent image. The developing device 2 irradiates light on the corresponding recorded image to form an electrostatic latent image. In the developing device 3, the charged toner 4 is electrostatically attached to the latent image on the surface of the photoreceptor 6 to form a visible toner image 5a. The toner image 5a on the photosensitive drum 6 is moved to the position where the transfer roller 7 contacts due to the rotation of the photosensitive drum 6 in the direction of the arrow. In parallel with these actions, the recording material 20 is sent to the position of the conveying rollers 15a, 15b by a paper feed roller (not shown). After correcting oblique lines and other finishing operations, it is integrated with the adjustment on the photosensitive roller 6. The toner image 5 a is sent to the transfer roller 7 at the transport timing of the driving timing. During the process of the recording material 20 being sent to the transfer roller 7, the recording material thickness detection device 16 arranged above the conveying path is applicable to the paper standard of China National Standard (CNS) A4 (210 X 297 mm) ( Please read the precautions on the back before filling out this page) Γ -9-A7 B7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Invention description (7), the thickness of the recording material 20 is detected, and the signal is sent to the control Device 1 0 0. The transfer roller 7 forms a part of the transfer section B, and presses the recording material 20 fed to the photosensitive drum 6 while applying mechanical pressure and a transfer electric field from behind the recording material 20 to adjust the pressure on the photosensitive drum 6 The toner image 5 a is transferred to the recording material 20. Here, the voltage (transfer voltage) applied to the transfer roller 7 to generate the transfer electric field is caused by, for example, the cut-off ratio (ON and OFF of the pulse signal) of the input signal sent from the voltage control device 18 Time ratio), and can be arbitrarily and continuously change the output voltage of the power supply 19 is supplied. The transfer voltage corresponding to the thickness of the recording material is applied to the transfer roller 7. The recording material 2 0 may have a binding portion 20 a at a substantially central portion. At this time, the thickness of the recording material may be different around the binding portion 20 a. Therefore, it is necessary to change the voltage applied to the transfer roller 7. The recording material 20 to which the toner image 5 a is transferred is sent to the fixing portion D, and the toner image is melted by the heat and pressure between the fixing portions D to fix the image. The recording material 20 that fixes the toner image is discharged by a paper discharge roller (not shown). On the other hand, the residual toner 5 b attached to the photoreceptor drum 6 without being transferred to the recording material 20 is removed by the charge removing device 9 and then scraped off by the cleaner 10, and recovered to a not-shown Inside the waste toner box "Next, the control device 100 will be described. Fig. 2 is a block diagram showing the control device 100 of this embodiment, and particularly shows the control portion of the transfer section B in detail. The control device 100 is formed by a memory device that houses the control programs of the CPU 1〇1 and the CPU 1 〇1, such as the ROM1 〇3 and the RAM 1 0 2 of the memory necessary to execute the control program of the C PU 1 〇1. .

The printing control unit 106 can control the charging device 1, the exposure device 2, and the developing device 3 to form an image on the photosensitive drum 6. The motor control unit 108 can control the driving motor 21 of the photosensitive drum 6, the conveying rollers 15a, 15b and the fixing section D, etc., and can integrate the driving timing of the photosensitive drum 6 and the toner image 5a on the photosensitive drum 6 and the recording material 2 Transport timing of 0 〇 Transfer control unit 1 0 7 The thickness of the recording material 20 detected by the recording material thickness detection device 16 to find the most appropriate transfer voltage corresponding to the thickness, and send a certain amount to the voltage control device 18 signal. The timing and time of applying the transfer voltage to the transfer roller 7 are obtained by the detection result of the thickness of the recording material at the applied voltage timing calculation unit 110 and the applied voltage time calculation unit 11 1 respectively, and the signal is sent to the voltage Control device 18 Now, referring to Fig. 1, Fig. 3 to Fig. 5, the method of controlling the transfer of the toner image of the recording material 20 in such an electrophotographic apparatus will be described. After starting the transfer control, at timing T0, the motor control unit 108 generates a drive motor instruction signal to start the operation of the motor 21, and performs a rotation motor process (step 201). At timing T1, the paper feed end process is performed (step 203), and after the recording material 20 is sorted, the drive timing and conveyance timing of the toner image 5a on the photosensitive drum 6 are integrated to start the paper feed process (step 20) 4). Then, the recording material thickness detection process is started (step 204), and the thickness of the recording material in a state where the recording material thickness is not detected is set to 0. This paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297mm) I ~ -111 IX I (please read the precautions on the back and then fill out this page) _ 11-Printed by the Consumer Labor Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 5. Description of the invention (9) At timing T 3, the recording material 20 passes through the installation position of the thickness detection device 16 to read, for example, the thickness dl (step 205), and sends the value via the signal conversion unit 1 0 9 To the transfer control section 1 0 7. At timing T4, the first optimum transfer voltage generation process is started (step 206). In this step 206, the first optimal transfer voltage generation process corresponds to the thickness of the recording material, and the data corresponding to this thickness is selected and generated from the data table shown in Figure 5 previously stored in a memory device such as ROM103. (D 1) The most suitable transfer voltage (V 1) of the signal is sent to the voltage control device 18 by the transfer control unit 107. The relationship between the thickness of the recording material and the optimal transfer voltage (VI) is shown in Figure 6. When the recording material becomes thicker, the optimal transfer voltage also becomes higher. By changing the voltage control signal generated from the voltage control device 18 based on the data shown in FIG. 5, the most suitable transfer voltage is sent from the power supply 19 for transfer to the transfer roller 7. This timing is obtained by separating the time difference T0 from the timing T3 for reading the thickness of the recording material. That is, the time difference T0 at the timing T4 is equal to the time that the recording material 20 is transported from the installation position of the recording material thickness detection position 16 to the transfer portion B where the transfer roller 7 and the photosensitive drum 6 contact each other. That is, when the recording material 20 reaches the transfer roller 7 and the photosensitive drum 6, the transfer voltage is applied. If the output voltage of the power supply 19 for transfer is slow in the rising characteristic, then consider its characteristics and set the time difference T 〇 to be shorter so that the most suitable transfer can be output before reaching the printing area of the recording material 20 Voltage. Alternatively, the photosensitive drum 6 may be temporarily stopped, and the photosensitive drum 6 may be rotated after the transfer voltage reaches a certain value.

The paper tray 55 borrowed from the first guide and the second guide The paper guides 5 6 and paper guides 1 7 form a transport path that can transport the booklet 20 of the recording material from the right to the left in the figure. This transport path is equipped with transport rollers 15c, 15d as transport devices , 15b, 15a. Among them, the transport rollers 15 e, 15 a are supported by elastic members 53, 54 such as springs, respectively, in order to be able to cope with a booklet that binds a large number of sheets until the thickness of the sheet changes, and the elastic members 53, 54 It is supported by driving sources 51, 52 such as solenoids to control the force of the transport rollers 15c, 15a to push the booklet 20. In this embodiment, the transport rollers 15c, 15d, 15b, 15a and the transfer roller 7 are driving rollers. Furthermore, if the booklet 20 is not thick, the driving sources 51 and 52 may not be used. The transport rollers 15c, 15a can also be used as driven rollers. The conveying roller 15 c is also a fixing roller that changes the toner image adhered to the booklet 20 of the recording material by electrical suction or the like into a permanent image. Therefore, the fixing roller 15 c is equipped with a heat source or a temperature detector, etc.> the thickness detectors 16a, 16b can detect the thickness of the booklet 20 entering the printing section. Based on the thickness data detected by the detectors 16a and 16b, the force to push the transfer roller 7 upward to the photosensitive drum 6, the voltage applied to the transfer roller 7 from the variable high-voltage power supply 19, and applying the above push Power and timing of the voltage. The description of the fixing section is omitted here, but the heat and pressure can make the toner image transferred to the recording material such as the booklet 20 as a permanent portrait. Furthermore, the variable high-voltage power supply 19 is grounded. This paper uses the Chinese National Standard (CNS) A4 specification (2 丨 0 X 297mm) (please read the notes on the back before filling out this page) i D18-A7 printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 3G6985 _Έ._ V. Description of the invention (16) The transfer roller 7 is composed of conductive rubber and a metal core, and a high voltage is applied by a variable high-voltage power supply 19. At the same time, the spring 8 and the solenoid 50 can be used to control the force applied by the transfer roller 7 to the photoreceptor tube 6. A charging device 1, an exposure device 2, a developing device 3, etc. are provided near the photoreceptor tube 6. The toner 4 is moved to the photosensitive drum 6 by the developing device 3 to form a toner image. Furthermore, the distance between the transport roller 15 d and the transfer roller 7 and the transport roller 15 b and the transfer roller 7 is at least shorter than the length in the transport direction when the booklet 20 is closed. Referring again to FIGS. 15 to 19, the operation of the electronic photograph control device according to the fourth embodiment of the present invention will be described. As shown in FIG. 15, the booklet 20 is transported on the paper tray 55 by the transport rollers 15b, 15a to X Direction, and the booklet 20 is detected by the detector 6. The booklet 20 stops at a predetermined position surrounded by the photosensitive drum 6 and the transfer roller 7 in the transfer section. At this time, in order to prevent the transfer roller 7 from becoming a resistance to the insertion of the booklet 20, the first page of the surface of the booklet 20 is bent or corrugated, and the driving source solenoid 50 reduces the force applied to the transfer roller 7 . As shown in FIG. 16, the photoreceptor barrel 6 rotates in the direction of rotation B, and the photoreceptor barrel 1 is charged by the charging device 1, the electrostatic latent image forming process is performed by the exposure device 2, and the photoreceptor device 3 The toner image forming process is performed on the cartridge 6. Furthermore, the speed at which the booklet 20 moves to the left in the figure (the X direction in Figure 15) corresponds to the speed at which the photosensitive drum 6 moves in the B direction. Then, as shown in Figure 17, when the booklet 20 is transported in the X direction and comes into contact with the photoreceptor 6, the thickness information detected by the thickness detector 16a will be applied.

Invention description (17) Calculated voltage The variable high-voltage power supply 19 is added to the transfer roller 7. At the same time, the most suitable amount of deformation is applied from the solenoid 50 to the spring 8 etc., so that the most suitable transfer pressure calculated from the thickness information is applied to the booklet 20, and the transfer roller 7 applies a certain pressure to the booklet 20. . Furthermore, the reason for changing the pushing force of the transfer roller against the photoreceptor cartridge such as a booklet by the driving source of a solenoid or the like is that, as shown in Figure 20, foaming by EP DM or silicon etc. For the transfer rollers made of conductive rubber, etc., the amount of deformation t 1, t 2, t 3, etc., the reaction force is increased by a quadratic curve rather than a straight line. Therefore, the thickness of a recording material such as a booklet is several tens of times greater than the thickness of a sheet of paper. Therefore, the pushing force applied to the booklet is at least several tens of times. As also shown in Figure 21, when the pressure between the photoreceptor tube and the recording material such as a booklet reaches 200 g / crri or more, there will be an obstacle in the middle. For example, when the contact area during transfer is 2.17 crri, when the force applied between the photoreceptor drum and the transfer roller exceeds 4 3 4 g, an obstacle in the middle of the gap will occur. The obstacle to this intermediate gap is that part of the toner image formed on the photoreceptor drum is not transferred to the recording material such as a booklet, so the part of the recording material where the toner should be present is not adjusted. Toner, the obstacle of the recording material directly exposed on the surface, especially means that there is no toner in any area. The transfer roller is fixed, and when the transfer roller is deformed corresponding to the thickness of the recording material, the thickness of the cutting paper (thickness is about 0.1 ram) deforms the rubber part of the transfer roller, and the reaction pressure generated by the transfer pressure , It will produce this paper standard using the Chinese National Standard (CNS) A4 specification (210X297 mm) a ^ i— · ^^^ 1 nn nn nn ml a ^^ i · 、 一 -eJ ^ · (please first Read the precautions on the back and then fill out this page) -20-A7 B7__ printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs 5. Description of the invention (18) The transfer pressure of the obstacles in the middle is the small pressure P1. However, the thickness above 0.2rara or the booklet, etc., will produce the transfer pressure of P 2 or P 3. Therefore, obstacles in the middle of the gap will occur, and the transfer pressure must be controlled. Furthermore, as shown in FIG. 18, when the toner image must also be transferred near the binding portion of the booklet 20, the transfer roller 7 must be pressed with a pressing force greater than the pressing force during the transfer . This is because an air layer is formed between the pages of the booklet 20 near the binding part, which is easy to form a local swell. In order to squeeze most of this swell, it is necessary to use the most suitable pressing force as usual. Pressure push. However, if the swelling in the vicinity of the binding portion of the booklet 20 can be removed before entering the transfer portion surrounded by the photosensitive drum 6 and the transfer roller 7, there is no need to change the above-mentioned pressing force. As shown in FIG. 19, when the booklet 20 is discharged from the transfer section by the transport rollers 15c, 15d, etc., the transfer of the toner image on the photosensitive drum 6 to the recording material such as booklet 20 is completed. Action, the conveying roller 15 c or driving roller 15 d applies heat and pressure to the booklet 20, so that the toner image on the booklet 20 becomes a permanent image. Furthermore, Figures 1 to 1 The electrophotographic apparatus shown in FIG. 9 omits the control apparatus not shown. Since this is a conventional technique, the explanation is omitted. Next, referring to Fig. 22, a booklet printer according to another embodiment of the present invention will be described. As shown in the figure, the booklet printer 200 is at least composed of an insertion port 301, transport rollers 302, 303, 306, 307, 322, 324 '326, transport path 360, magnetic information reading unit 304, and magnetic information recognition unit 3 3 0, the image reading part 3 0 5, the image information recognition part of the paper standard is applicable to the Chinese National Standard (CNS) A4 specifications (21〇Χ297 mm) —I n ^ it ^ l ^ iv — ^^ 1 im ^ ^^^ 1 ^ ilft mi.

Description of the invention (21) When the second print density value that is not a problem in operation is higher than the signal, the signal will be requested from the computing department through the control department to request maintenance. , To the operator via an external computer or the operation unit (not shown) of the booklet printer. The booklet 3 3 3 shown in Figure 23 is formatted by the booklet printer 300 shown in Figure 22. The so-called format printing refers to the 337 (format) column in the booklet in the blank state, for example, as shown in Fig. 23, printed with date, symbol, amount A, amount B, balance, etc. However, the thickness of the booklet 3 3 3 is bounded by the binding part 3 3 8. The thickness of the booklet 3 3 3 varies depending on the number of pages, and it easily expands near the binding part 3 3 8. Therefore, it is possible to fix on the booklet without deforming the toner image by controlling the pushing pressure during fixing. The electrophotographic apparatus described in the first to fourth embodiments described above may also form an electrostatic latent image on the photoreceptor barrel 6 by the exposure device 2 as shown in the figure, while a conventional copying machine scans the document to latent image on the photoreceptor barrel 6. In this way, for example, a document can be copied on a notebook, and the library can be copied on a notebook. As shown in FIGS. 14 to 19, the electronic photographing device is transported by rollers 15c, 15d. As indicated by arrow X in FIG. 18, the booklet 20 is transported out. After the transfer roller 7 finishes copying, the control device acts to reverse the transport rollers 15c, 15d, the transfer roller 7, the transport rollers 15a, 15d, and the booklet 20 is returned to the insertion side of the electrophotographic device. In this way, the number of parts of the electronic photographing device can be reduced. For users, the booklet 20 can be quickly returned to the hand, and a high-efficiency electronic photographing device can be realized. Furthermore, the embodiment uses a photosensitive cylinder to form a latent image, but any shape can be used as long as it can sense light. For example, a ribbon may also be used.
