A process cartridge is provided that is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes a photosensitive drum and a developing roller. A coupling member is provided adjacent to one axial end of the developing roller, with the coupling member including a driven portion, an intermediary portion, and a driving portion. A retaining portion is also provided, with the retaining portion configured and positioned to retain an axis of the driving portion of the coupling member in a position that is deviated from the axis of the developing roller in a direction crossing the axis of the developing roller so as to enable engagement of the driving portion with a driving member of the image forming apparatus when the process cartridge is inserted into the main assembly of the apparatus with the developing roller being in contact with the photosensitive drum.
