ABSTRACT:
An electrophotographic copying machine is of the type which starts, in response to the actuation of a copy start switch, its copying operation after a pre-copy process is conducted to stabilize the property of a photoreceptor. The copying machine comprises a selection circuit and a timer. The selection circuit is operated to start the timer upon the termination of a previous copying operation. During a time as set for the timer, the pre-copy process is carried out following the termination of the previous copying operation. In response to the actuation of the copy start switch, the following copying operation is started just following the termination of the previous copying operation.
