摘要:
An image forming apparatus sets one of a plurality of modes including a monochrome mode of forming a monochrome image, converts a multivalued luminance signal into signal values of color material amounts to be used to form the image and forms the image using color materials based on the signal values. The color materials used in the forming when the monochrome mode is set include an achromatic color material and at least two auxiliary color materials which have hues opposite to each other and a chroma larger than that of the achromatic color material.
