    Abstract: 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.

    Abstract translation: 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 。

    Abstract: 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.

    Abstract: When a fixing device becomes uncontrollable and a large amount of electric power is continuously supplied to the heater, concentration of mechanical stress on a heater is suppressed, whereby shear fracture of the heater is prevented from occurring. A longitudinal region of the heater in which a heat generation resistive member is provided is supported by a heater support surface of a heater holder, and an opposed surface of the heater holder that is opposed to a longitudinal region of the heater in which the heat generation resistive member is not provided is designed not to be in contact with the heater.

    Abstract: An image forming apparatus having a sharp neutralizing member which can perform uniform neutralizing effects for a long period of time. The sharp neutralizing member includes sharp projections in which tip portions having the following relationship between a distance P between the tip portions of neighboring projections and the distance D between the tip portion of the projection and an object of neutralization:D≧4.0 mm, and 0.8*D≦P≦1.5*D. Particularly for neutralization of a carrier of toner images, it is possible to achieve uniform neutralization of the medium and to provide a high-quality image.
