1. An image forming apparatus comprising:
a rotary body;
a supporting member that detachably and rotatably supports a portion of the rotary body, the rotary body being detachable from the supporting member when moved in a detachment direction;
a rotatable member that rotates around a rotation axis of the rotary body, rotation of the rotatable member being independent of rotation of the rotary body; and
a force-converting mechanism that converts a rotation force generated by the rotation of the rotatable member into a force whereby the rotary body moves in the detachment direction thereby detaching from the supporting member.
