  • 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.

  • Patent number: 9838568
    Abstract: An image reading apparatus and an image forming system are provided which can reduce the influence of magnification error, detect patches in correct positions, and save the sheets required for adjusting an image. The image reading apparatus makes use of an image scanner which reads patches printed on a sheet P, a spectral colorimeter which colorimetrically measures the patches read by the image scanner, and is provided with a timing compensation unit which compensates the colorimetric measurement timing with which colorimetric operation of the spectral colorimeter is triggered based on the positional information of the patches read by the image scanner, and an image correction unit which corrects the color information of the patches read by the image scanner based on the colorimetric values of the patches colorimetrically measured by the spectral colorimeter.
