摘要： An image forming system includes a post-processing unit capable of performing a post-processing on the sheet on which the toner image is formed. The image forming system is capable of executing a transfer cleaning operation to move toner from a transfer member to an image bearer by electrostatic force caused by cleaning bias applied by a bias applying unit in a state where the image bearer and the transfer member are rotated, to clean the transfer member, as an inter-sheet operation performed when at least one of inter-sheet areas that exist on the image bearer during a successive image forming period. The image forming system is capable of executing a rotation stop operation to stop rotation of the image bearer and the transfer member, as the inter-sheet operation when the post-processing is performed, in addition to the transfer cleaning operation, before or after the transfer cleaning operation is executed.

摘要： An image forming apparatus is provided in which, during a continuous sheet passing, in the case where a between-sheets time is short, none of a cleaning mode and a drive OFF mode is performed; in the case where the between-sheets time is of a medium length of time, the cleaning mode is performed but the drive OFF mode is not performed; and in the case where the between-sheets time is long, both the cleaning mode and the drive OFF mode are performed. As a result, degradation of an image bearer due to the cleaning bias is alleviated, decreased productivity due to the cleaning mode is alleviated, a problem is alleviated in which a back surface of a recording medium gets dirty due to toner adhered to a transfer rotation body, and another problem is alleviated in which the service life of a driven member is shortened.
