1. A fuser unit comprising:
a cylindrical member that has flexibility; a nip member that is disposed to slidingly contact an inner surface of the cylindrical member; and a backup member that is driven by a driving force and configures a nip region between the backup member and the cylindrical member on the nip member, wherein the cylindrical member includes folded-back portions formed at outer sides of a recording-sheet conveyance region in a recording-sheet width direction by folding back entire circumferences of both ends of the cylindrical member outward, wherein a contact surface of the folded-back portions contacting the backup member has concaves and convexes, the concaves and convexes configured by at least one cut-off portion provided to each of the folded-back portions, and wherein the cut-off portions are notches formed at inner edges of the folded-back portions in the recording-sheet width direction.
