<p>A process cartridge usable with an electrophotographic image forming apparatus, a main assembly of which is not provided with a mechanism for moving a main assembly side engaging portion provided in the main assembly to transmit a rotational force to an image bearing member in the direction of the rotational axis of the image bearing member by an opening and closing operation of a cover member for the main assembly. The process cartridge can be mounted to the main assembly in a direction substantially perpendicular to the rotational axis of the image bearing member without deterioration of the usability performance. With the process cartridge, the electrophotographic image forming apparatus can be downsized. in accordance with the movement of the process cartridge when the process cartridge is dismounted from the main assembly of the electrophotographic image forming apparatus, a coupling member which is inclinable and translatable relative to a rotational axis of a rotational force transmitted member enters an inside of the recess of the main assembly side engaging portion to receive the rotational force from the main assembly engaging portion.</p> |
