Abstract
A cylindrical heat generating belt in an image heating apparatus includes a heat generating layer, in which an electroconductive filler is dispersed in a resin material, for generating heat by being supplied with electric power; and a surface parting layer. The heat generating layer has a sheet resistance, with respect to a generatrix direction of the heat generating belt, which is larger than that with respect to a circumferential direction of the heat generating belt.
