Abstract:
An electrophotographic apparatus employing a self-heat-emitting heating roller capable of causing current to flow through a heat emitting resistor at a time of turning on a power supply until a maximum electric power to be consumed in the electrophotographic apparatus, to thereby shorten a rising-up time of the heating-roller fixing apparatus. The drive starting temperature is previously set and the heat emitting resistor is selected so as to satisfy the following inequalities:V.sup.2 /R.sub.3 .ltoreq./V.sup.2 /R.sub.2
