SOLUTION: A drive gear 111 on a device main body side is constituted to rotate by a prescribed angle with respect to a drive shaft 110. Even when the addenda of both gears butt against each other when a developing unit 1 is rotated and the developing gear 14 of a developing device is meshed with the driving gear 111, the drive gear 111 is rotated so as to relax impact by butting. |
