Abstract
An image having a quality superior to that of the prior art is obtained even if there are multiple causes of image degradation. In a color image forming apparatus that includes a plurality of rotating bodies for forming a color image by rotating in cooperation, amounts of fluctuation in the rotational speeds of the rotating bodies that cause a decline in the image quality of the color image are detected for every rotating body (i.e., for every cause) and the detected amounts of fluctuation are corrected appropriately.
