摘要： A fixing device includes a roller, a pressing member pressed against the roller, such that when a sheet having an unfixed image is passed thorough a nip formed between the roller and the pressing member, the unfixed image is fixed on the sheet, a first heater configured to heat the roller, a second heater configured to heat the pressing member, and a controller configured to control the second heater, such that a time-averaged heat generation by the second heater when an image of a decolorable material is fixed is greater than a time-averaged heat generation by the second heater when an image of a non-decolorable material is fixed.

摘要： In accordance with an embodiment, an image forming apparatus comprises an image forming section, a fixing section and a controller. The image forming section forms a toner image with at least one selected from a first toner having a first fixing temperature area and a second toner having a second fixing temperature area of which a lower limit fixing temperature is higher than the first toner. The fixing section fixes the toner image on the sheet. The controller controls a standby temperature of the fixing section to a temperature lower than the lower limit fixing temperature of the second fixable temperature area.

摘要： An image forming apparatus includes a fixing device configured to fix a toner to a recording medium, a cooling device disposed so as to cool the fixing device with forced air, and a rotatable guide configured to guide the recording medium towards a first location when in a first position and towards a second location when in a second position. The rotatable guide partially blocks the forced air at the first position and forms a pathway for the forced air when at the second position. A control unit rotates the guide unit to the second position if an operating mode of the fixing device is changed from a first mode having a fixing temperature set point at a first temperature to a second mode having a fixing set point temperature lower than the first temperature.

摘要： In accordance with an embodiment, an image decoloring apparatus comprises a conveyance path configured to convey a sheet on which an image is formed with a coloring agent that is decolored by heat; a first heat roller configured to be arranged at the upstream side of the conveyance path; and a second heat roller configured to be arranged at the downstream side of the conveyance path. Each of the first heat roller and the second heat roller includes a cylindrical portion and a heat source. The thickness of the cylindrical portion constituting the first heat roller is larger than the thickness of the cylindrical portion constituting the second heat roller. In this way, the heat capacity of the first heat roller is also larger than the heat capacity of the second heat roller.
