Abstract
An image heating apparatus includes a cylindrical film, and a heater having a substrate, and a heat generating element provided on the substrate. The heater has an elongated plate-like shape, and a first surface contacting the film, a second surface opposite to the first surface, and a heater lateral surface facing outwardly in a widthwise direction of the heat generating element. A supporting member supports the heater, and includes a recess and a supporting lateral surface that is parallel to and opposes the heater lateral surface. The supporting lateral surface is provided in the recess, and is bonded to the heater lateral surface using an adhesive material. A high heat conduction member has a thermal conductivity greater than a thermal conductivity of the substrate, and contacts the second surface of the heater and is sandwiched between the heater and the supporting member.
