Claims (9)

Using a plurality of kinds of nozzles provided for discharging different amounts of droplets, respectively, a recording head having energy generating means for generating discharge energy for discharging liquid droplets from each nozzle, the energy generating A recording apparatus configured to perform recording by discharging droplets from the nozzle toward the recording medium by driving means;
Driving means for driving the energy generating means;
Control means for controlling the drive means,
The control means is a small nozzle for discharging a relatively small amount of liquid droplets of the plurality of types of nozzles according to at least one of a driving state of the energy generating means and an environmental condition around the recording head. Droplets ejected from the small nozzle and the large nozzle for ejecting a relatively large amount of droplets at at least one dot formation scheduled position to be formed on the recording medium by the droplets ejected from A recording apparatus, wherein the drive means is controlled to land.   The recording apparatus according to claim 1, wherein the driving state of the energy generating unit is a driving stop time from a previous droplet discharging operation to a current droplet discharging operation in the small nozzle. The control means includes a first dot formation planned position among dot formation planned positions to be formed by droplets ejected from the small nozzle after the drive stop time of the small nozzle has elapsed for a predetermined time or more. The recording apparatus according to claim 2, wherein the driving unit is controlled to land droplets to be ejected by the small nozzle and the large nozzle at a predetermined number of dot formation scheduled positions. 4. The recording apparatus according to claim 1, wherein the environmental condition around the recording head is at least one of an environmental temperature and an environmental humidity around the recording head. The control means, the relative formation planned position of the dot to be formed on the recording medium by the droplets discharged from the small nozzles, the number of formation should do dot by the droplet ejected from the large nozzle, wherein 5. The recording apparatus according to claim 1, wherein the recording apparatus is changed according to at least one of a driving state of the energy generating means and an environmental condition around the recording head.   The recording head includes at least one nozzle group in which nozzle rows each including a plurality of nozzles are arranged to face each other, and in one nozzle row among a pair of nozzle rows belonging to the same nozzle group. 6. The recording apparatus according to claim 1, wherein the amount of droplets ejected from each nozzle is different from the amount of droplets ejected from the nozzles in the other nozzle row. The recording medium is conveyed in the arrangement direction of the nozzle rows of the recording head by a conveying unit,
The recording apparatus according to claim 1, wherein the recording head reciprocates along a main scanning direction intersecting a recording medium conveyance direction by the conveyance unit. The recording head has a plurality of the nozzle groups arranged along the main scanning direction,
The nozzles in one nozzle row of each nozzle group are arranged so as to be positioned between the arrangement positions of the nozzles in the other nozzle row, and at least two sets of the nozzle groups are among the plurality of nozzle groups. The recording apparatus according to claim 7, wherein droplets of the same color are ejected and are arranged symmetrically in the main scanning direction. The energy generating means is driven using a recording head having a plurality of types of nozzles provided for discharging different amounts of liquid droplets and energy generating means for generating discharge energy for discharging ink from the nozzles. A recording method in which droplets are discharged from the nozzles toward the recording medium for recording,
Liquid droplets ejected from a small nozzle for ejecting a relatively small amount of liquid droplets of the plurality of types of nozzles according to at least one of the driving state of the energy generating means and the environmental conditions around the recording head. The energy generation so as to land the droplets ejected from the small nozzle and the large nozzle for ejecting a relatively large amount of droplets at a part of the dot formation scheduled position to be formed on the recording medium by A recording method comprising controlling the driving of the means.
