Claim 13:
14. A fixer comprising:
a heating body arrangement having a sheet-passing region, the sheet-passing region coming into contact with a sheet to fix an image to the sheet moving in a first direction, the heating body arrangement including a film-shaped cylindrical body, a substrate, and a heating body, the film-shaped cylindrical body having an axis extending in an axial direction, and the heating body being wider than the sheet-passing region in the axial direction orthogonal to the first direction;
a heat transmission arrangement disposed on an opposite side to a first surface of the heating body, with the heating body interposed between the heat transmission arrangement and the first surface, and the heating body having an outer end disposed outside an outer end of the sheet-passing region in the axial direction, the substrate arranged between the heat transmission arrangement and the heating body, the heat transmission arrangement being wider than the substrate in the axial direction; and
a roller configured to form a nip with the film-shaped cylindrical body at the heating body,
wherein the heating body is arranged to generate heat inside the outer end of the sheet-passing region in the axial direction,
wherein the heating body arrangement includes a plurality of heating body elements, the heating body elements located at different positions in the axial direction, and the substrate supporting the plurality of heating body elements, and
the heat transmission arrangement is formed of a material with higher heat conductivity than the substrate.
