Abstract
An image forming apparatus includes a rotary fixing member cleaner that includes a freely rotatable rotary unwinding member, around which a cleaning web winds, a rotary winding member to wind the cleaning web thereon from one end thereof, and a load applicator to apply a load to the cleaning web unwound from the rotary unwinding member. The rotary fixing member cleaner removes any unnecessary substance adhering to an outer circumferential surface of the rotary fixing member therefrom by unwinding and moving the cleaning web from the rotary unwinding member in an opposite direction to a direction of movement of the outer circumferential surface of the rotary fixing member at a contacting point at which the cleaning web contacts the outer circumferential surface of the rotary fixing member. The load applicator presses against the cleaning web winding around the rotary unwinding member at a prescribed angular contact position.
