Abstract:
1. An image forming apparatus comprising: an image input section operable to input a multicolor image; a mixing ratio input section operable to input a first mixing ratio which includes first ratios for mixing each of a plurality of color components; a calculating section operable to calculate a second mixing ratio which includes second ratios for mixing each of the plurality of color components according to the input first mixing ratio so that a sum total of the second ratios is made to be substantially constant; and a forming section operable to mix the plurality of color components of the multicolor image in response to the calculated second mixing ratio, thereby forming a first monochrome image; wherein in a case where the first ratios of each of the plurality of color components are equal to each other, the calculating section calculates the second mixing ratio so that the second ratios of each of the plurality of color components are equal to each other.
