Abstract
An image heating apparatus heats a toner image formed on a recording material, and includes: a heater including a substrate and a heat generating resistor thereon for generating heat for heating the toner image, by electric power supply; an electric power shut-off member operable in response to an abnormal temperature rise of the heater to shut off the electric power supply; and a heat conduction member having a thermal conductivity, in a direction of a thickness of the substrate, higher than that of the substrate. The contact area between the heat conduction member and the substrate is larger than the contact area between the heat conduction member and the electric power shut-off member.
