Abstract
Multiple layer fuser belts having a rigid or semi-rigid substrate layer and a high conformability, low surface energy elastic layer. The substrate layer is formed from long-life material such as polyimide. Apertures, beneficially elongated diamonds, are cut into the substrate layer such that the substrate layer can stretch slightly along the circumference of the fuser belt. The elastic layer is bonded to the substrate layer and is made from a highly conformable, low durometer material having a low surface energy. When the fuser belt is partially wrapped around a driven roller so as to form a nip with a pressure roller the fuser belt stretches in the direction of belt motion. As the fuser belt passes through the nip the fuser belt contracts, releasing surface strain, and thus reduces sticking between the fuser belt and fused toner.
