ABSTRACT:
A color image forming apparatus separately corrects an intensity of each of color component images used for forming a multicolor image. The multicolor image is formed by superimposing a plurality of color component images on a printing paper. Each of the color component images is formed by one of color toners. Color patterns having a gradation are printed by using each of the color toners. A color sensor is provided at a position in which each of the color patterns is read, the color sensor being sensitive to a color of each of the color toners. The color sensor outputs output signals corresponding to each of the color patterns. The intensity of each of the color component images is corrected in accordance with the corresponding output signals of the color sensor. A mixture of colors in each of the color component images is detected, and the intensity of the corresponding color component image is corrected so as to maintain a desired color balance.
