ABSTRACT:
A digital color copying machine comprising a test mode is disclosed. In the test mode, image data corresponding to a partial area of an original document indicated is stored in a RAM, and thereafter, the image data stored in the RAM is read out repeatedly, and plural test images for which the color correction is made with different color tones respectively are formed as a mosaic monitor image on a recording medium. Then, one of plural test images is selected, and a copy of document having a color tone of the selected test image is produced. The test mode is canceled if a test image has not been selected during a predetermined time period.
