Abstract: PROBLEM TO BE SOLVED: To obtain stable sliding characteristics of a plain bearing of a cartridge type developing device for a long period of time low friction and without the fluctuation in the coefficient of friction as against an environment change such as a temperature change. SOLUTION: A resin composition molding of the plain bearing consisting of a molding of the resin composition used for a sliding section of a developing device is formed by compounding a silicone oil not having a reactive functional group with a polyolefin resin at 0.5 to 20 wt.% of the entire part of the resin composition.

Abstract: PROBLEM TO BE SOLVED: To provide a peeling board which is excellent in all toner non-adhesion, heat resistance, mechanical strength, and flexibility and further can be produced at low cost.
SOLUTION: The peeling board 1 consists of a metal plate 2 of which the surface is coated with a fluorinated polyether polymer to peel off paper from a fixing member of an electrophotographic apparatus. In the metal plate 2, the surface roughness Ra of the paper feeding side 2a with which paper is brought into contact satisfies Ra ≤1 μm, the fluorinated polyether polymer is applied at least to the surface of a portion close to the fixing member as a coat layer 3 and the fluorinated polyether polymer is a polymer having -C
x F
2x -O- (x is an integer of 1 to 4) as a main structure unit and has a terminal bonding with at least one polar group.
