A cartridge includes a drum flange provided at one end portion of a photosensitive drum, with the drum flange including a hollow interior portion elongated along the axis of the photosensitive drum and an interior surface. A coupling member is operatively connected to the drum flange, with the coupling member being configured to transmit the driving force to the drum flange. A coil spring is provided for urging the coupling member, and at least a part of the coil spring is positioned within the hollow interior portion of the drum flange. The interior surface of the drum flange includes an abutting portion configured to restrict movement of the coupling member in the direction away from the photosensitive drum along the axis of the photosensitive drum by abutting the coupling member.
