Abstract
A cartridge for a main assembly of an electrophotographic image forming apparatus, wherein the main assembly includes a rotatable driving coupling member including a driving force transmitting portion for transmitting a driving force and a driving side abutment, wherein the cartridge is demountable in a direction substantially perpendicular to a rotational axis of the driving coupling member, includes a rotatable driven coupling member including a driving force receiving portion for receiving the driving force, and a driven side abutment to be abutted by the driving side abutment, the driven coupling member being slidable in a predetermined direction which is substantially parallel with a rotational axis of the receiving coupling member; wherein at least one of the driving side abutment and the driven side abutment is inclined so that the driven coupling member is retractable away from the driving coupling member in the predetermined direction by a force received by driven side abutment from the driving side abutment, and wherein a distance between the rotational axis of the driven coupling member and the abutment of the receiving abutment is not more than a distance between the rotational axis of the driven coupling member and the driving force receiving portion.
