Abstract

PURPOSE:To suppress waste of power to the utmost and to save energy consumption, by rendering start times of preliminary arrangements for the units of a copying machine different from one another so as to complete the preliminary arrangements for all the other units almost at the same time as that of completion of the preliminary arrangement of the unit requiring the longest time. CONSTITUTION:An image forming apparatus 10 is provided with a device for charging a photoreceptor 11 and detecting a state of moisture absorption and dew condensation in accordance with a state of its charged potential, and a drum heater 28. On closing a maintenance power supply switch, said detector is allowed to detect a state of moisture absorption and dew condensation of the photoreceptor 11, and when this detected value indicates incapability of use of the photoreceptor 11, it is heated and dried, and the apparatus 10 is disabled to form an image till the photoreceptor becomes able to be used, thus permitting waste of heat energy caused by always keeping the heat dryer in an operable state to be prevented and heat economy to be enhanced.
