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. |
