<P>PROBLEM TO BE SOLVED: To improve mounting property of a process cartridge on a main assembly of an electrophotographic image forming apparatus. <P>SOLUTION: The process cartridge includes: a first frame that rotatably supports a photoreceptor drum; a second frame that rotatably supports a developing roller and is rotatably coupled with the first frame around an axial line so as to allow the photoreceptor drum and the developing roller to be in contact with each other and to be separated from each other; and a shaft coupling member disposed at an axially one end of the second frame, the coupling member including a drive input section where driving force to rotate the developing roller is inputted, and allowing the drive input section to relatively move with respect to the second frame in a direction intersecting the axial direction of the second frame. The process cartridge can be mounted on the main assembly of an electrophotographic image forming apparatus while the developing roller is separated from the photoreceptor drum. The process cartridge includes a biasing member that imparts bias force to the second frame so as to press the developing roller to the photoreceptor drum. <P>COPYRIGHT: (C)2012,JPO&INPIT |
