Abstract
An image forming apparatus includes an image forming station for forming a toner image on a sheet; a heating member and a pressing roller that form a nip for fixing the toner image on a sheet; a heat absorption roller for absorbing heat by contacting the pressing roller; a moving mechanism for moving the heat absorption roller to and away from the pressing roller; a detector for detecting an abnormal state that heat absorption roller remains contacted the pressing roller; and a controller for controlling an interval between adjacent sheets when image forming operation is continuously carried out for a plurality of sheets, wherein when the detector does not detect the abnormal state, the controller supplies the sheets at a first feeding interval, and, when the detector detects the abnormal state, the controller supplies of the sheets at a second feeding interval longer than the first interval.
