Abstract
An image forming apparatus cartridge includes a rotatable member rotatably supported in a casing to permit rotation about an axis of the rotatable member, a developer roller rotatably supported in the casing to permit rotation about an axis L, and a coupling member having an axis Labout which the coupling member is rotatable and a free end portion for receiving a rotational force. The free end portion of the coupling includes at least two projections that are positioned at least partially outside of the casing, with each of the at least two projections being open to the axis L. The coupling member is operatively connected to the rotatable member and the developer roller in order to transmit the rotational force to the rotatable member and the developer roller.
