Filed: 1985-06-11
Abstract: PURPOSE:To eliminate a defect in cleaning by setting the length from a transfer position to the position of a recording paper tail detection part longer than the length from a development position on an image carrier to the transfer position and stopping a developing function when the tail of recording paper is detected by a detecting means. CONSTITUTION:The length L1 of the paper path between a sensor A and the transfer position is set longer than the distance L2 of the surface of a photosensitive body between the development position and transfer position and a sensor B is provided at a distance of the length L2 of the paper path from the transfer position. The sensors turn on when recording paper passes over the sensors and turn off again when it finishes passing, and microswitches, etc., are used. Consequently, there is no untransferred part corresponding to the tail of the recording paper because a circuit is so constituted as to stop the rotation of a developing device the moment the sensor A detects the tail of the recording paper or stops development in response to a potential at which an image is not developed. Consequently, magnetic brush cleaning is carried out without causing any defect in cleaning and the photosensitive body is held invariably clean to realize electrophotography of high quality.
