Abstract
A fuser has a heater, a heat roller, an endless belt, a pressure pad, and a slidable sheet. The pressure pad forms a nipping portion to nip the endless belt between the pressure pad and the heat roller. The slidable sheet is interposed between an inner circumferential surface of the endless belt and the pressure pad in the nipping portion. The slidable sheet includes a plurality of dents and a plurality of projections on a surface contacting the inner circumferential surface of the endless belt. The plurality of dents are arranged in a first part of the surface of the slidable sheet. The first part is located in a range corresponding to the nipping portion. The plurality of projections are arranged in a second part of the surface of the slidable sheet. The second part is located in a range corresponding to a portion different from the nipping portion.
