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.

Abstract: Provided is a development cartridge mounted on a main body of an image forming apparatus. The development cartridge includes a photoconductive unit, a developing unit coupled to the photoconductive unit so as to rotate to a development position and a release position, and an elastic member that provides an elastic force to maintain the developing unit at the development position. A switching member is mounted on a rotation shaft of the developing roller to be rotatable about a rotation shaft of a developing roller. The switching member is switched to a first state where the switching member contacts an interfering portion of the photoconductive unit and rotates the developing unit to the release position and to a second state where the switching member is separated from the interfering portion and allows the developing unit to rotate to the development position due to the elastic force of the elastic member.
