Abstract
An image forming apparatus including a formation unit for forming patch images for calibration of an output image, a detection unit disposed on a paper conveyance path and configured to detect the fixed patch images formed on paper by the formation unit, and a correction unit for performing the calibration using the patch images detected by the detection unit is provided. When the formation unit forms the patch images, the formation unit arranges the images on both sides of a medium. On the front surface of the medium, a low-density patch image is formed, and on the back surface of the medium, a high-density patch image is formed. Alternatively, a media on which the patch image is formed is discharged once, and a user turns the medium upside down and feeds the medium again such that the first and second patch image formation positions differ from each other.
