  • Patent number: 10682868
    Abstract: A heating device includes rollers, a heating belt, a heater and a hardware processor. The heating belt is in partial contact with an image generation face of a recording medium and extends over the rollers and circulating in cooperation with the rollers. The heater heats the heating belt. The hardware processor modifies an area of contact between the recording medium and the heating belt. At least two rollers are disposed along a traveling direction of the heating belt and are urged to the recording medium with intermediation of the heating belt. The hardware processor modifies the area of the contact by modifying a distance between a first roller and a second roller among the at least two rollers, the first and second rollers being respectively disposed most upstream and most downstream in the travelling direction of the heating belt.
