Abstract
The image forming apparatus includes: an apparatus body including a drive source; a driven member detachably attachable to the apparatus body; a first transmission member in the apparatus body, including a base rotatable around a rotation axis, and transmitting drive force from the drive source to the driven member; and a second transmission member in the driven member, including a base rotatable around the rotation axis, and transmitting drive force from the first transmission member to the driven member. Any of the first and second transmission members includes a projection, and the other includes a receiving port. The receiving port receives the projection when a rotation angle between the first and second transmission members is an angle set in advance while not receiving the projection when the rotation angle is out of the angle, at the time of mounting the driven member on the apparatus body.
