摘要： An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.

摘要： An image forming apparatus is capable of setting a cleaning mode in which a fixing portion is cleaned by a cleaning sheet while nip-conveying the cleaning sheet in a fixing nip. When the cleaning mode is set, an image forming apparatus provides a period in which a first rotatable member and a second rotatable member are rotated in a state in which a heater is controlled so that a surface temperature Th of the first rotatable member immediately after passing through the fixing nip is kept within a temperature range of Th≦Tf3, wherein Tf3 is a flow start point of a toner and so that a surface temperature Tp of the second rotatable member immediately after passing through the fixing nip is within a temperature range Tf2≦Tp≦Tf3, wherein Tf2 is a deformation end point of the toner.

摘要： An image forming apparatus, which is configured to form an image on a sheet, includes an image forming unit configured to form an unfixed toner image on the sheet, and a fixing unit configured to fix the unfixed toner image to the sheet by heating the sheet bearing the unfixed toner image while conveying the sheet by a fixing nip portion. The image forming apparatus can perform a cleaning mode for cleaning the fixing unit by conveying a sheet with an unfixed toner image for cleaning formed thereon by the fixing nip portion. At a time of the cleaning mode, the image forming unit forms the unfixed toner image for cleaning on a sheet surface opposite from a sheet surface where the unfixed toner image is formed at a time of image formation.

摘要： The image forming apparatus comprises: a first driving section causing an image carrying body carrying a developer image to perform regular rotation or reverse rotation; a fixing section fixing the developer image and conveying a sheet; a second driving section rotating the fixing section; and a control section. The control section controls the first driving section to cause the image carrying body to perform regular rotation such as to convey the sheet and transfer onto the sheet the developer image formed on the image carrying body, and controls the second driving section to cause the fixing section to fix the developer image on the sheet. Further, in a state that the fixing section nips but does not convey the sheet, the control section controls the first driving section to cause the image carrying body to perform reverse rotation so that the image carrying body is cleaned using the sheet.
