ABSTRACT:
An image forming apparatus reciprocally operates one of the image forming body units and the document feeding units. A first control circuit produces signals necessary for image formation operation, while keeping an automatic document feeder in a wait state. A second control circuit operates the automatic document feeder only when the image formation operation is not in progress. Therefore, the power source which is provided can be shared between the image forming body unit and the automatic document feeder without the necessity for excess capacity.
