Abstract
A fuser is equipped with a heating roller, fixing belt, pressure roller, pad, and spring. The heating roller is located on the downstream side of the fixing belt with respect to the sheet conveyance direction, and as the heating roller rotates, contacts the sheet toner side of a sheet, heating the sheet. The fixing belt contacts the side of the sheet opposite to the toner side of the sheet. The pressure roller comes into contact with the heating roller via the fixing belt. The pad is of a softer material than the fixing belt, and, as the pad exerts a force on the heating roller by pressing on the fixing belt, a downstream side of the pad with respect to the sheet conveyance direction is inclined away from the pressure roller. Springs urge the pad toward the pressure roller and the heating roller.
