Abstract:
In an image forming apparatus, when photosensitive members 4Y, 4M, 4C are in contact with a transfer belt, then color adjustment is performed. When the photosensitive members 4Y, 4M, 4C are not in contact with a transfer belt, i.e., only a photosensitive member 4Bk is in contact with the transfer belt, then only black adjustment is performed.
