    摘要： A fixing device includes a first support and a second support to rotatably support a fixing rotator at a first lateral end and a second lateral end of the fixing rotator in an axial direction thereof. A first stopper is mounted on the first support. A second stopper is mounted on the second support. A first skew restraint projects from an outer circumferential surface of the fixing rotator radially at the first lateral end of the fixing rotator in the axial direction thereof. A second skew restraint projects from the outer circumferential surface of the fixing rotator radially at the second lateral end of the fixing rotator in the axial direction thereof. The second skew restraint comes into contact with the second stopper as the fixing rotator moves in the axial direction thereof toward the first support.

    摘要： A fixing device includes a rotatable, endless fixing belt; a rotatable contact member configured to contact a circumferential surface of the fixing belt to form a nip in association with the fixing belt; and a heating member disposed at an interior surface of the fixing belt, configured to heat the fixing belt. The heating member includes a multiple heat sources arranged along the width of a sheet of recording media in a direction perpendicular to a sheet conveyance direction. A controller changes an area to be heated by each heat source based on image data and corresponding to an unfixed image on the sheet. The fixing belt is heated by the heating member so that the unfixed image on the sheet that has been conveyed to the nip is fixed onto the sheet at least with heat. The heating member is disposed at a portion other than the fixing nip.

    摘要： A fixing device includes a fixing rotary body, an opposed member, a heater, and a heating controller. The opposed member opposes the fixing rotary body to form a nipping portion therebetween. The heater includes heat generators arranged in a width direction of a recording medium. When the recording medium fed to the nipping portion has an image area and a non-image area, the heating controller controls the outputs of the heat generators based on image information so that a first heat generator of the heat generators corresponding to the image area is higher in temperature and a second heat generator of the heat generators corresponding to the non-image area is lower in temperature. Based on information other than the image information, the heating controller temporarily shifts an area of the fixing rotary body corresponding to the non-image area to a temperature differing from a normal temperature.

    摘要： An image forming apparatus includes an image forming part, a fixer including a heating member and a pressure member, a reverse transport part to forward a recording medium transported from the fixer to the image forming part, a toner image sensor to detect presence of a toner image on the recording medium, and a controller. When a glossy image formation mode is selected and no toner image is detected on the recording medium, the image forming part does not form a toner image on the recording medium, the fixer performs a first heating and pressing process and transports the recording medium to the reverse transport part, the reverse transport part transports the recording medium to the image forming part, the image forming part forms a toner image on the recording medium transported from the reverse transport part, and the fixer performs a second heating and pressing process and fixes the toner image thereon.
