ABSTRACT:
A process cartridge is detachably mountable to an electrophotographic image forming apparatus main assembly. The main assembly includes a main assembly electrical contact, first and second projections, main assembly positioning portions, and a force application member. The cartridge includes first and second frames, a first-frame drum, first and second portions, a second-frame developing roller, a second-frame force receiving portion, a regulating portion, a first-frame memory, a cartridge electrical contact, and a first-frame recess and a second-frame recess. When the cartridge is set in the main assembly, the cartridge electrical contact moves integrally with the main assembly electrical contact by the first frame recess engaging the first main assembly projection and the second frame recess engaging the second main assembly projection, upon the first frame rotating about the first portion and the second portion by the force receiving portion receiving the force from the force application member.
