Abstract: In one aspect of the invention, a fixing apparatus that heats a recording material having a toner image while conveying the recording material at a nip portion to make the toner image fix onto the recording material includes a cylindrical belt having a heat generating layer that generates heat by being energized and a contact for supplying electricity to the heat generating layer. The contact is in contact with one of an outer surface and an inner surface of an end of the belt in the generatrix direction of the belt. An electrically conductive layer is provided, along the direction of rotation of the belt, on a surface of the heat generating layer opposite to a surface of the heat generating layer at which the contact is present.
