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.

Image forming apparatus, image processing unit, and image forming method to keep image quality precision of both sides of recording medium, and computer product

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.
