In a cartridge structure that uses a coupling member which can tilt and which can couple with a rotational force transmitting part of an electrophotographic image forming device, in a case where the attaching and removing direction and the development/separation direction of the cartridge with respect to the electrophotographic image forming device are different, the coupling member can't couple with the rotational force transmitting part of the electrophotographic image forming device. In the present invention, provided are: a coupling lever 55 that, in unison with the attachment or detachment of a development cartridge B1, abuts and retracts from a coupling member 180; and a coupling spring 56 that causes the coupling lever 55 to impart an impelling force to the coupling member 180. |
