摘要： The image forming apparatus, includes a conveyor belt for bearing a recording material, capable of suppressing an image blur caused by a separating discharge at the separation of the recording material from the conveyor belt. To fix record materials on a transportation belt, the recording material is charged by a adhering member to electrically adhere the recording material to the conveyor belt. When the recording material is separated from the conveyor belt, a separating discharge occurs between the recording material and the conveyor belt, as the recording material is charged. In order to reduce the faulty of the toner image on the recording material caused by the separating discharge, the voltage applied to the adhering member is controlled for example according to a current which the recording material receives at the transfer position to mutually cancel the charge received at the transfer position by the adhering member.
摘要翻译：图像形成装置包括用于承载记录材料的传送带，能够抑制在记录材料与传送带分离时由分离排出引起的图像模糊。为了将记录材料固定在传送带上，记录材料被粘附部件充电以将记录材料电粘附到传送带上。当记录材料与传送带分离时，由于记录材料被充电，所以在记录材料和传送带之间发生分离放电。为了减少由分离放电引起的记录材料上的调色剂图像的故障，施加到粘合部件的电压例如根据记录材料在转印位置接收的电流来控制，以相互取消收到的电荷在粘接部件的移动位置。

摘要： A toner image formed on an image bearing member is transferred onto a recording material so as to overflow from an edge portion of the recording material, thereby enabling the toner image to be formed so as to extend to the edge portion of the recording material. To suppress the deposition of the toner in the edge portion of the recording material, a cleaning member for cleaning the edge portion of the recording material obtained after the fixing is provided. In order to make a trailing edge of the recording material come into contact with the cleaning member, the recording material which has passed through a fixing apparatus is temporarily switched back, thereby allowing the trailing edge portion of the recording material to collide with the cleaning member.

摘要： A compact image forming apparatus is provided in which stains on the back of a transfer material can be prevented. In particular, in a marginless print mode in which a toner image can be formed to the edge of a transfer material, a large amount of toner adheres to a transfer-material bearing member. The image forming apparatus includes a collecting member that can temporarily collect the toner adhering to the transfer-material bearing member. The toner that is temporarily collected by the collecting member is transferred to an intermediate transfer member and is cleaned by a cleaning unit.
