Abstract (en)
The improvement of precision of the surface temperature control of a photoreceptor drum is intended. A CPU (28) determines whether the copying machine is in a waiting state or in a copying state or in an initial calibration state and decides the amount of output to a drum heater (19) by a fuzzy reasoning according to the state of the copying machine. The fuzzy reasoning is performed based on information from a sheet size sensor (31), a drum surface temperature sensor (23) and a room temperature sensor (32). <IMAGE>
