摘要： The image forming apparatus includes a fixing apparatus capable of restraining offset of a toner in multifarious types of sheets and in a variety of environments at low costs. The fixing apparatus has a rotary fixing member and a nip forming member which forms a fixing nip portion by coming into contact with the rotary member. A recording material bearing an unfixed toner image is conveyed while being pinched by the nip portion. The fixing apparatus fixes a toner image onto the recording material. The fixing apparatus further has a bias applying means which applies a bias to the nip forming member. The bias applying means, before the recording material reaches the nip portion, applies a first bias to the nip forming member so that a surface of a rotary member is charged with electricity, and applies a second bias to the nip forming member while the recording material is conveyed by the nip portion.

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.

摘要： The speed at which transfer-material enters a transfer region is controlled to prevent a phenomenon in which a toner image on an intermediate transfer belt is scraped by the leading edge of the transfer-material when the toner image is transferred onto the transfer-material. While the conveying speed of the transfer-material in a transfer nip coincides with the speed of the intermediate transfer belt, the transfer-material is conveyed at a speed lower than the peripheral speed of the intermediate transfer belt when the leading edge of the transfer-material comes into contact with the intermediate transfer belt, and the conveying speed of the transfer-material is increased by the time when the transfer-material enters the transfer nip.

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.
摘要翻译：形成在图像承载部件上的调色剂图像被转印到记录材料上以便从记录材料的边缘部分溢出，从而使调色剂图像形成为延伸到记录材料的边缘部分。为了抑制调色剂在记录材料的边缘部分中的沉积，提供了用于清洁在定影之后获得的记录材料的边缘部分的清洁部件。为了使记录材料的后缘与清洁部件接触，已经通过定影装置的记录材料暂时转回，从而允许记录材料的后缘部分与清洁部件碰撞。
