Abstract
An image forming apparatus includes a photosensitive drum, a cleaning blade, and a movement mechanism. The movement mechanism reciprocates the photosensitive drum in an axial direction of the photosensitive drum in a specific cycle. The movement mechanism includes a first cam gear and a second cam gear. The first cam gear rotates about an axis of the photosensitive drum together with the photosensitive drum. The second cam gear is restricted in position in the axial direction and rotates at a rotational speed different from that of the first cam gear. The first and second cam gears each have a plurality of coaxial cam portions. When top points and bottom points of the respective cam portions come in contact with one another by turns, the photosensitive drum moves in the axial direction.
