The surface heating fuser system which has low energy consumption and high heating up speed is introduced. The seamless heating tube is designed and fabricated by extrusion process with composite material of carbon nano tube and liquid silicone rubber. In order to minimize the heat capacity, a thin film layered heating material tube is selected. For interconnecting between heating material and electrical supply unit, electroplated nickel conductor and carbon brush are adopted. Numerical analysis is performed to predict the heat transfer characteristic of the fuser and its performance is tested and analyzed. The temperature control of the tube is the critical parameter so as to accomplish the fusing performance. The printing speed of the proposed fuser structure is up to 40ppm.
