ABSTRACT:
An apparatus for controlling a fusing temperature in a system using an electrophotographic developing process by sensing the thickness of the paper. An apparatus for controlling a fusing temperature in a system using an electrophotographic developing process having a fusing lamp for generating heat to execute a fusing operation, a fusing temperature detecting device for generating a detection value according to the change of the fusing temperature of a heat roller, a sensing device for discriminating the kind of the paper according to the detection of the thickness of a conveyed paper, a controller for comparing a value set according to the kind of the paper discriminated from the sensing device with the detection value detected by the fusing temperature detecting device to thereby generate a control signal controlling driving of the fusing lamp to control the fusing temperature, and device for driving the fusing lamp in response to the control signal.
