策ではない。2. Description of the Related Art Conventionally, with respect to a pressure roll, a fixing pressure roller in which a silicone rubber foam layer (foam) having a skin layer on the outer surface is integrally molded on a roll-shaped core metal, and a method for manufacturing the fixing roller are known. Are known. (JP-A-63-183
However, in the above structure, a skin layer is formed on the outer surface of the foamed layer, but the surface of the layer in contact with the core metal (hollow inner wall surface) remains in the foamed state. Compared with the case of solid rubber, there is a drawback that the adhesion area to the cored bar is small and the degree of foaming varies, so that the adhesion to the cored bar is poor. Therefore, when such a roller is used in combination with a heat roller, for example, the torque generated by the heat roller during rotation causes cohesive failure of the foam layer near the interface between the core metal and the foam layer, There was a problem with the durability of the roller. On the other hand, in order to deal with this problem, there is also known a pressure roller having a two-layer coating structure in which a surface in contact with a core metal is coated with solid rubber, and then a silicone rubber foam layer is further coated thereon. In this case, since the manufacturing process becomes complicated, the productivity is low and it is not a good idea.

性に応じて適宜選択すればよい。A feature of the present invention is that a skin layer (2) having a constant thickness is provided on the hollow inner wall surface of the silicone rubber foam (3). By doing so, the contact area between the foam and the core metal (1) is increased, and there is no concern about the variation in the degree of foaming that is often seen in the foam layer.
The adhesive strength is dramatically improved. Regarding the thickness of the skin layer (2), if it is too thin, the adhesion durability with the core metal will not be improved,
If the thickness is too thick, the hardness will be too high, so that the thickness is preferably in the range of 0.2 mm to 1.0 mm. On the other hand, the thickness of the silicone rubber foam (3) is not particularly limited, and is within the range adopted in this field, that is, 1.0.
It may be appropriately selected from the range of mm to 7.0 mm. Next, a method of manufacturing the fixing roller of the present invention will be described. Here again, the method of forming the skin layer (2) on the hollow inner wall surface of the silicone rubber foam (3) is the center. In the present invention, first, a raw material is prepared by adding a vulcanizing agent and a foaming agent to silicone rubber. At this time, the compounding ratio of the vulcanizing agent and the foaming agent may be appropriately selected according to the required hardness of the roller. First, the raw material silicone rubber is formed into a tube shape, for example, by an extruder. Next, in the present invention, the silicone rubber foam (3) is finally obtained.
In order to form a stable skin layer (2) having a sufficient thickness on the hollow inner wall surface of the tube, the tubular molded body after extrusion molding and before vulcanization / foaming by heating is heated to room temperature (usually 15 ° C to 20 ° C).
Temperature or aging at low temperature (50 ℃ to 70 ℃)
℃). This normal temperature standing or low temperature aging step is the most characteristic part of the present invention. Therefore, at this stage, the skin layer (2) has not been formed yet. At this time, leave it at room temperature for at least 24 hours or longer (desirably 72 hours or longer) and at low temperature aging for 8 hours or longer (desirably 24 hours or longer). A stable and sufficiently thick skin layer (2) can be obtained. Next, while the tubular molded body left at room temperature is placed in a heating furnace and heated to vulcanize and foam to obtain the silicone rubber foam (3), a stable skin having a sufficient thickness is formed on the hollow inner wall surface. Form the layer (2). The heating condition at this time is that the temperature is 150 ° C to 30 ° C.
It is preferable that the temperature is 0 ° C. and the heating time is in the range of 5 minutes to 60 minutes. At this time, a hot air circulating machine or a bead vulcanizing furnace is used as the heating furnace. Simultaneously with this, a similar skin layer is formed on the outer surface of the hollow cylindrical silicone rubber foam (3). Finally, the hollow cylindrical silicone rubber foam (3) is coated and fixed on the core metal (1) via an adhesive or the like, whereby the core metal (1) and the silicone rubber foam (3) are formed. To form a fixing pressure roller integrated through the skin layer (2). further,
After this, a polishing step of polishing the roller surface may be added. Incidentally, it goes without saying that the silicone rubber tube may be produced by using a method of injecting liquid silicone rubber into a mold in addition to the extrusion molding method using an extruder as described above. Yes. In the present invention, iron, SUS, and aluminum are suitable as the material of the core metal. The size of the core metal itself is such that the axial length is 250 mm to 400 mm and the outer diameter is about 6 mm to 30 mm. If roughening treatment such as sandblasting is performed on the outer periphery of the cored bar in advance, the adhesive strength with the silicone rubber foam that coats the cored bar in a later step is improved. Further, there is no particular restriction on the adhesive, and a typical silicone rubber-based adhesive is typically adopted. In addition, there is no particular restriction on the thickness of the adhesive, and it may be appropriately selected according to the required characteristics of the roller. Good.

Vulcanizing agent (Shin-Etsu Chemical Co., Ltd., trade name "C-3")
A silicone rubber material containing 3.5 parts and 6 parts of a foaming agent (Toray Dow Corning Silicone Co., Ltd., trade name "MR-34") is extruded by an extrusion molding machine. Then, the silicone rubber molded body was aged at 60 ° C. for 24 hours at a low temperature, and then heated and vulcanized at 200 ° C. for 30 minutes to form a skin layer having a thickness of 1 mm on the inner wall surface and also having a thickness of 1 mm on the outer wall surface. A silicone rubber foam on which a skin layer is formed is prepared. Finally, the silicone rubber foam on which the skin layer was formed was placed on an aluminum core metal having an outer diameter of 10 mm and a length of 300 mm, which was coated with an adhesive (manufactured by GE Toshiba Silicone Co., Ltd., trade name "TSE322"). By coating, a fixing pressure roller having an outer diameter of 30 mm, a hardness of 30 degrees (Asker C) and a foaming density of 220% was obtained, and the total pressure between the core metal and the silicone rubber foam layer was 12.
Peripheral velocity 100mm / sec, 200 with 0N system load distribution
A free running test at 1500 ° C. for 1,500 hours showed sufficient interfacial durability with an adhesive strength of 1000 gf / cm 2. By the way, in the above example, the same operation was performed except that the formation of the skin layer was omitted, and in the single layer roll coated with the silicone rubber foam layer, the adhesive strength with the core metal was 700 gf after the above spinning test. It was only / cm2.
