Image forming apparatus and cartridge used for the same

A cartridge attachable to an image forming apparatus including an apparatus main body and a movement member, the cartridge comprising:

• at least one rotating member;
• at least one coupling arranged to engage with a drive member on the apparatus main body side so as to receive a drive force to rotate the at least one rotating member, the at least one coupling including a projected portion provided at an end portion thereof and engaging with the drive member;
• and
• a contacted portion with which a contact portion of the movement member is brought into contact,
• wherein the movement member moves the cartridge and is movable between a first position for disposing the cartridge at a position where image formation is possible and a second position where the cartridge is disposed outside of the apparatus main body and attachable to and detachable from the movement member,
• wherein, when the movement member is positioned at the first position, the at least one coupling is arranged to engage with the drive member so as to be positioned at a drive position where the at least one coupling is able to rotate the at least one rotating member,
• wherein the at least one coupling is movable to a retracted position from the drive position, and, with respect to a rotational axis direction of the at least one rotating member, a position of the projected portion when the at least one coupling is positioned at the retracted position is different from a position of the projected portion when the at least one coupling is positioned at the drive position, and
• wherein, in response to the moving member having moved from the first position to the second position, the cartridge is moved by the contacted portion being pushed by the contact portion, and the at least one coupling moves from the drive position to the retracted position.
