Abstract
Official abstract text for this publication.
An image heating apparatus includes a heating member for heating a toner image on a sheet; a fan; a duct provided with an opening for discharging air supplied by the fan, toward the heating member; a shutter for the opening; a motor for moving the shutter; a detector for detecting that the shutter is in a predetermined position; and a controller for controlling the motor; wherein when the detector does not detect the shutter after a predetermined time elapses from production of first instruction for moving the shutter toward the predetermined position, the controller produces second instruction for moving the shutter in a direction away from the predetermined position.
