ABSTRACT:
A color-shift correction image is formed in a density D and it is determined whether the color-shift correction image can be detected successfully. If the color-shift correction image can be detected successfully, then the density is decreased. If the color-shift correction image can not be detected successfully, then the density is increased. In this manner, the minimum density is determined.
