  • Image forming apparatus, image processing unit, and image forming method to keep image quality precision of both sides of recording medium, and computer product
    Patent number: 7062185
    Abstract: When a reading unit reads information of a pattern image for correcting image quality printed on at least either side of a recording medium, a control unit compares the information of the pattern image for correcting image-quality with correction pattern information that is a basis of the pattern image for correcting image quality transferred to the at least either side of the recording medium, and controls an image forming unit based on a result of the comparison to correct image quality on the at least either side of the recording medium.

  • Double-sided image forming apparatus and method
    Patent number: 7016636
    Abstract: In a double-sided image forming apparatus and method, back-side images are developed on a first middle transfer belt prior to developing of front-side images on the first middle transfer belt, and the back-side images are transferred to a second middle transfer belt. The number of back-side images allowed to be supported at a time on the second middle transfer belt is determined. The number of back-side images are developed on the first middle transfer belt prior to developing of the same number of front-side images on the first middle transfer belt. The front-side image of the first middle transfer belt and the back-side image of the second middle transfer belt are simultaneously formed on both sides of a copy sheet.
