Abstract

An image forming apparatus includes an alternative printing unit. The alternative printing unit performs alternative printing of a black image by mixing images of color materials of three colors of cyan, yellow, and magenta. The alternative printing unit includes a color material amount control unit that controls amounts of the respective color materials, which form the images of the color materials of the three colors, so as to be smaller than those at a time of normal printing.
