Claim 10:
11. An image forming apparatus comprising:
at least one image former configured to form an image on a sheet;
a heating body arrangement having a sheet-passing region, the sheet-passing region coming into contact with the sheet to fix the 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;
a roller configured to form a nip with the film-shaped cylindrical body at the heating body; and
a controller configured to allow the heating body to generate heat inside the outer end of the sheet-passing region in the axial direction,
wherein the heat transmission arrangement comes into contact with a second surface opposite to the first surface of the heating body arrangement,
wherein the heat transmission arrangement includes first and second heat transmission bodies separated from each other in the axial direction, and
inner ends of the first and second heat transmission bodies are disposed inside the outer end of the heating body in the axial direction.
