Abstract

PURPOSE:To reduce a driving load and also to simplify a driving device, by stopping both a non-photosensitive substance segment and a magnet roller when the non- photosensitive substance segment has reached a position of the magnet roller, and rotating both of them by synchronizing them when copying. CONSTITUTION:A photosensitive body 1 has photosensitive substance segments A, B, in other part, a non-photosensitive substance segment is formed. A driven gear 22 of a magnet roller 5 is engaged with a gear 23 of a roller 2, and they are driven by a main driving motor 16 through a clutch 24 by a control signal. According to this constitution, when the photosensitive body 1 is rotated half and the non- photosensitive substance segment reaches a position of the roller 5, both of them are stopped once, are rotated half by the next control signal and are stopped, and during this time, formation of a prescribed latent image, and its transfer are executed, and said operation is repeated. In this way, the photosensitive body 1 and the roller 5 are rotated and stopped by one control signal, the driving load is reduced, and since the driving system to be provided is one, its driving device is simplified.
