Electrostatic copying apparatus

摘要

An electrostatic copying apparatus comprising a rotating endless photosensitive material, an image-forming means for forming an image on the photosensitive material, a conveying means for conveying through a predetermined passage a copying sheet to which the image formed on the photosensitive material is to be transferred, and a cleaning means for cleaning the photosensitive material after image transfer. In the performance of one copying cycle, the image formation is completed before the photosensitive material has rotated through one turn from the starting of image formation, but the photosensitive material is further kept in rotation for cleaning. When a plurality of copying cycles are performed successively, the starting point of image formation in the next copying cycle is selectively set on the basis of the length in the conveying direction of the copying sheet conveyed through the passage during the previous copying cycle.
