Abstract
The image heating apparatus includes a tubular shaped film; a backup member configured to be brought into contact with an outer surface of the film; a heater having an elongated shape and being configured to be brought into contact with the film, the heater including a substrate and a heat generating resistor formed; a first heat conductive member having a higher thermal conductivity than the substrate and being configured to be brought into contact with a surface of the heater, the first heat conductive member including divided first heat conductive members arranged with a gap formed therebetween; a pinching member configured to pinch the first heat conductive member; and a second heat conductive member provided in a region of the gap so as to be brought into contact with both of the heater and the pinching member.
