    • 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.
    • 多层定影带具有刚性或半刚性基底层和高适形性的低表面能弹性层。 基材层由诸如聚酰亚胺的长寿命材料形成。 孔径有利的细长金刚石被切割成基底层,使得基底层可沿着定影带的圆周稍微伸展。 弹性层结合到基底层上,并由具有低表面能的高度适形的低硬度的材料制成。 当定影带部分地缠绕在从动辊上以与压力辊形成压区时,定影带沿着皮带运动的方向伸展。 当定影带穿过辊隙时,定影带收缩,释放表面应变,从而减少定影带和熔融调色剂之间的粘附。
