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.

Abstract: A colorimetric device includes: a feeding unit configured to feed a transfer medium; a colorimeter configured to perform colorimetry of an image that is formed on the transfer medium and that has a color boundary in a feeding direction; and a colorimetry control unit configured to control the feeding unit and the colorimeter, wherein the colorimetry control unit acquires color information related to the color boundary of the image and determines the color boundary of the image based on the color information and a result of the colorimetry performed by the colorimeter.
