A heat roller for an electrophotographic device comprised of an internal tube inside an insulating layer wherein a heating element having a resistance member is fixed to the outer surface of the insulating layer by depositing the resistance member onto a polyimide film applied to the insulating layer, depositing the resistance member directly to insulating layer, or embedding the resistance member in the insulating layer. Alternatively, the heating element having a resistance member is fixed to the outer surface of the internal tube by depositing the resistance member onto a polyimide film applied to the internal tube, thereby eliminating the insulating layer. An elastomer layer of predetermined thickness is overmolded to the outer surface of the insulating layer or the internal tube and an outside surface is applied to the outer surface of the elastomer layer wherein a toner image is fused on paper from the outside surface by heat transferred from the heating element.
