Abstract: An image forming apparatus includes a control portion configured to output, in a test mode, a recording member which has passed through a fixing nip portion in a case of a first temperature difference in which a center part temperature of a first rotary member is higher than an end part temperature of the first rotary member and a recording member which has passed through the fixing nip portion in a case of a second temperature difference in which the center part temperature is lower than the end part temperature by one operation of starting test mode to the input portion.

Abstract: An image forming apparatus includes an image forming device, a fixing device including a first rotary member of which a surface layer containing a fluororesin is brought into contact with a sheet surface having an unfixed toner image formed by the image forming device, and a controller. In a case that image formation processing for continuously forming a toner image on a plurality of predetermined sheets is executed, the controller can control conveyance of a sheet so that a portion of the surface layer of the first rotary member which is brought into contact with a trailing edge of a preceding sheet is brought into contact with a margin area on a leading edge side on a next sheet.

Abstract: An image heating apparatus includes first and second rollers forming a nip therebetween to heat a toner image on a sheet; a rubbing roller for rubbing an outer surface of said first roller; a moving mechanism for moving said rubbing roller between a contact position for contacting with said first roller and a spacing position spaced from said first roller; a measuring portion for measuring time elapsed from start of a rubbing process; a controller for discriminating, upon receipt of image heating instructions during the rubbing process execution, whether to continue the rubbing process or to interrupt the rubbing process and execute the image heating process, on the basis of the time measured by said measuring portion.
