Abstract
A cylindrical film for use with an image heating apparatus includes a plurality of heat generating elements configured to generate heat by a flow of a current, in which each of the heat generating elements has a ring shape and is arranged along a longitudinal direction of the film; a ring-shaped insulating portion configured to electrically insulate the heat generating elements adjacent to each other; and a heat conductive layer different from a layer of the heat generating elements with respect to a thickness direction of the film, The heat conductive layer is 3 W/mK or more in thermal conductivity and overlaps with the heat generating elements with respect to the longitudinal direction.
