Abstract
A device for transmitting a rotational force to an electrophotographic photosensitive drum includes a flange connectable to the photosensitive drum and having a rotational axis, a hollow portion, and a force receiving surface, a pin configured to transmit the rotational force to the flange, and a coupling member the coupling member including a shaft shaped portion extended along a rotational axis of the coupling member and including a through-hole portion. When the pin and at least a part of the shaft shaped portion of the coupling member are accommodated in the hollow portion of the flange and the pin contacts the force receiving surface, the pin is capable of transmitting the rotational force received from the coupling member to the flange.
