COLOR IMAGE FORMING DEVICE

摘要

PROBLEM TO BE SOLVED: To solve a problem that the color blur can not be calculated correctly because of the influence of the remarkable image formation unevenness due to the reference color derivation when a registration pattern is read for measurement of the color deviation in an image forming device which is used as an output device of computer, etc. SOLUTION: In this color image forming device, the detection error is minimized of color deviation quantity due to the generated image formation unevenness by preliminarily measuring the generated image formation unevenness of respective color based on the color of the image with minimum formation unevenness as the reference color.
