Abstract

PURPOSE:To enable good quality copies to be obtained from the beginning even after the machine has not been in operation for a long time by beforehand rotating its photosensitive drum for a specified time prior to image formation and increasing or decreasing the number of idle revolutions according to the standing time. CONSTITUTION:At the first rotating of a photosensitive drum 1, an original 6 and transfer paper p are not conveyed and the copying machine is in a standby state, during which time the photosensivive drum 1 is radiated evenly over the entire circumference by way of the optical system of exposure lamps L1, L2, reflecting mirror MR, lens LS, whereby the degree of fatigue of the photoreceptor is returned to the specified fatigue state. In the second rotation of the photosensitive drum 1, the original 6 is sent in synchronization therewith and the original images are formed on the photoreceptor by way of the optical system and are developed by a developing device DE. If a timer which measures the downtime for which the machine has been left standing without making copying is added and the number of idle revolutions of the photosensitive drum 1 is increased or decreased in proportion to the downtime, the much better and stable images are obtainable.
