Abstract
A digital color copying machine provides for setting a specific area of an original document and storing image data of the specific area with respect to gradation of color of the original document. The color of the image data contained in the image memory can be compensated by iteration of the color image forming process. A plurality of images, each having a differently compensated color can be provided in different positions on one of the copy sheets as transferred from the original document.
