Abstract

PURPOSE: To even the degrees of fatigue of segments and even the picture quality of a series of copies by evening the frequencies of use of all the segments in an electrostatic copying machine provided with plural photoreceptor segments.
CONSTITUTION: Photoreceptor segments A and B are installed on the peripheral surface of a drum 1 by means of fittings 2, 2', 3, 3'. As a start button is operated, an original is fed and the drum 1 rotates in the arrow direction from the position illustrated. The photoreceptor segment B out from a cleaning device 9 passes through a charger 4, exposure part 5 and developing device 6, transfers the image onto copying paper with a transfer device 7, goes through a destaticizer 8 and is again subjected to cleaning in cleaning 9, thence the above operations are repeated. In succession to the photoreceptor segment B, the photoreceptor segment A also performs the similar operations. If it is assumed that, e.g., photoreceptor segment A is used for the final copy, arrangement is so made that the drum 1 stops in the illustrated position past the position of the cleaning device 9. Then it turns out that in the next copying the use is started from the segment B
