Abstract
Abstract An image forming system includes a generator for generating a pattern signal with a plurality of tonality levels. An image forming apparatus is movable in relation to an image forming medium, and includes a plurality of image forming stations sequentially arranged, for each of a plurality of color components, in a relative movement direction of the image forming medium. Each of the image forming stations form an image for each color component the basis of the pattern signal. A circuit is provided for discriminating a reproduction condition of tonality in accordance with the formed color image. A color balance of the color image formed by the image forming apparatus is controlled, in accordance with the result of discrimination by the discriminating circuit. A plurality of memories store a pattern signal for each color component and a plurality of image forming stations form an image for each color component on the basis of the pattern signal read out from the plurality of memories, respectively.
