摘要： A fuser unit includes: a cylindrical member; a heat generation member; a nip plate; a backup member that forms a nip portion; and a temperature detection member that detects a temperature of the nip plate. The nip plate has: a plate-shaped part that forms the nip portion; a lubricant restraint part that is formed on at least a part of a downstream side end of the plate-shaped part in a predetermined direction and that extends toward an inner side in a diametrical direction of the cylindrical member, and a detected part that extends from an end of the lubricant restraint part toward the predetermined direction. The detected part is formed to be shorter than the plate-shaped part in an axial direction of the cylindrical member, and both ends of the detected part in the axial direction are adjacent to a space.
