摘要： There is provided an image forming apparatus that can suppress the formation of creases when forming images on both surfaces of a sheet and can greatly reduce the incidence of unprinted areas. The image forming apparatus has a sheet stacking section in which sheets are stacked, a sheet conveying section that conveys a sheet, an image forming section that forms an image on the sheet while the sheet is conveyed, a re-conveying section that again conveys the sheet with the image formed on a first surface thereof to the image forming section, and a sheet feeding section that feeds a sheet from the sheet stacking section or the re-conveying section to the image forming section. When a sheet is fed from the sheet stacking section for image formation on the first surface of the sheet by the image forming section, the sheet is fed at a first speed, and when a sheet is fed from the re-conveying section for image formation on a second surface of the sheet by the image forming section, the sheet is fed at a second speed that is slower than the first speed and is slower than the speed at which the sheet is conveyed by the sheet conveying section.

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： 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： 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： 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.
