Abstract
A cartridge detachably attachable to a main body of an image forming apparatus is provided. The cartridge includes a rotary member and a cartridge coupler. The cartridge coupler includes a transmission member coupled to a rotation axis of the rotary member, a receiving member connected to a set coupler provided in the main body for transmission of power, and a connection member connecting the transmission member and the receiving member together. The receiving member has an Oldham structure allowing movement relative to the transmission member in an axial direction. The receiving member is movable to a first position at which a rotation axis of the receiving member is misaligned with a rotation axis of the transmission member in an attachment or detachment direction, and to a second position at which the rotation axis of the receiving member is aligned with the rotation axis of the transmission member.
