Abstract (en)
A structurally improved fusing roller assembly (200) based on the heat pipe principle is provided. The fusing roller assembly includes a fusing roller (212) and a heat pipe (262) coaxially mounted inside the fusing roller (212). A resistance heater (213) is helically wound around the exterior cylindrical surface of the heat pipe, and rests between the inner cylindrical surface of the fusing roller and the exterior cylindrical surface of the heat pipe. The heat pipe (262) is hermetically sealed. The sealed inner space (268) is partially filled with a working fluid (214). The surface of fusing roller (212) can be instantaneously heated up to a target fusing temperature. The fusing roller assembly (200) can be heated up to a target fusing temperature within a shorter period of time without need for warm-up and stand-by period, so that power consumption decreases. <IMAGE>
