Image forming apparatus, image forming method and program product

摘要

An image input section is operable to input a multicolor image. A mixing ratio input section is operable to input a first mixing ratio which includes first ratios for mixing each of a plurality of color components. A calculating section is operable to calculate a second mixing ratio which includes second ratios for mixing each of a plurality of color components according to the input first mixing ratio so that the sum total of the second ratios is made to be substantially constant. A forming section is operable to mix a plurality of color components of the multicolor image in response to the calculated second mixing ratio, thereby forming a first monochrome image.
