PROBLEM TO BE SOLVED: To provide an image forming apparatus that can suppress a change in rotation of a photoreceptor drum due to a behavior of a recording medium.SOLUTION: On the downstream of a drum driving gear 29 transmitting a driving force to a photoreceptor drum 1, a sleeve driving gear 30 transmitting a driving force to a developing sleeve 5 is arranged. The developing sleeve 5 is in contact with the photoreceptor drum 1. The photoreceptor drum 1 is rotated quickly to put a backlash of the drum driving gear 29 constantly in one direction, and thereby suppressing a change in load on the photoreceptor drum 1.SELECTED DRAWING: Figure 1 |
