摘要： The development device includes a development member and a circulation member. The development member develops an electrostatic latent image formed on a latent image carrier with a developer including toner and a carrier to make the electrostatic latent image visible. The circulation member receives the developer discharged from the development member and conveys the developer back to the development member. The circulation member includes a container provided upstream from the development member in a conveyance direction of the developer to store the developer. The container includes an agitator provided inside the container and agitates and mixes the developer and fresh toner supplied to the container. The agitator includes a rotatable agitation member in which one or more holes are formed through which the developer passes to mix the fresh toner and the developer to be agitated in the container.

摘要： An image forming apparatus includes an image bearer; a transfer rotator to contact the image bearer to form a transfer nip therebetween; a bias application device to apply, to the transfer rotator, a transfer bias, a cleaning bias to remove toner adhering to the transfer rotator, and a non-image area bias smaller in absolute value than the cleaning bias; and a controller to control the bias application device and set a sheet feeding interval according to a predetermined condition. When the sheet feeding interval exceeds a predetermined threshold, the controller causes the bias application device to apply, to the transfer rotator, the non-image area bias for an application time Z and the cleaning bias for a time X−Z within the sheet feeding interval when X represents the sheet feeding interval, and the application time Z is increased as the sheet feeding interval is increased.

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.

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 more 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.
