ABSTRACT:
An image forming apparatus is provided that forms an image using developers of different tone and the same hue. When forming images for measurement for density control, the apparatus performs density control by forming a greater number of density levels of an image for measurement developed using a light developer than the number of density levels of an image for measurement developed using a dark developer. Thus, even if the amount of applied light developer may fluctuate, the fluctuation can be compensated to prevent the occurrence of pseudo-contours that lower image quality.
