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.
