In an image forming apparatus, a rotating body has a follower member that is arranged to confront with a drive member in an axial direction of the drive member. A drive transmitting member transmits drive force from the drive member to the follower member by coupling the drive member and the follower member with each other, while allowing relative positional deviation between the drive member and the follower member on a plane perpendicular to the axial direction of the drive member within a prescribed range. The drive member and the follower member have a drive-member side contact part and a follower-member side contact part, respectively. A making-contact member brings the drive-member side contact part and the follower-member side contact part into contact with each other.
