An image forming apparatus includes a driver unit, a driver control unit, a drive gear, a drive-force output gear, and a driven unit. The drive gear is driven by the driver unit. The drive-force output gear is driven with the drive gear. The driven unit, detachable from the image forming apparatus, includes a rotating member, and a drive-force input gear. The drive-force input gear, engageable with the drive-force output gear when the driven unit is installed into the image forming apparatus, rotates the rotating member. The driver control unit controls the driver unit at a first driving speed to contact the drive gear to the drive-force output gear after an installation of the, driven unit. The driver control unit also controls the driver unit at a second driving speed for image forming operation. The first driving speed is set to a slower speed compared to the second driving speed.
