Abstract:
1. A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, wherein the main assembly includes a rotatable main assembly side engaging member having a recess and a rotational force applying portion provided in the recess, said process cartridge comprising: a photosensitive drum having a rotational axis substantially perpendicular to a mounting and demounting direction of said process cartridge; process means actable on said photosensitive drum; a cylindrical rotational force transmitted member for receiving a rotational force for rotating said photosensitive drum; and a coupling member held inside said cylindrical rotational force transmitted member and including (i) a rotational force receiving portion for receiving the rotational force from the rotational force applying portion and (ii) a rotational force transmitting portion for transmitting the rotational force to said cylindrical rotational force transmitted member, wherein said coupling member enters the recess of the rotatable main assembly side engaging member in a state that said process cartridge is mounted to the main assembly, and wherein said coupling member is inclinable and translatable relative to a rotational axis of said rotational force transmitted member to disengage from the rotatable main assembly side engaging member when said process cartridge is dismounted from the main assembly.
