An image processing apparatus includes an image forming instructing section that notifies an image forming section, whether to perform a first printing processing with a plurality of colors including at least one chromatic color or a second printing processing with only black. A data obtaining section obtains pixel data from a plurality of pixels constituting an image; and an operating section inputs designated color data. A pixel data extracting section extracts pixel data of colors, except for a designated color indicated by the designated color data inputted through the operating section, from pixel data obtained by the data obtaining section. A printing type selecting section selects the first or second printing processing based on each pixel data extracted by the pixel data extracting section. The image forming instructing section notifies the printing type selected by the printing type selecting section as the type of printing processing to be performed.
