Abstract
Disclosed is a color image forming apparatus in which a color image is formed by accumulating a visible image on an image transfer medium. The color image forming apparatus includes a plurality of forming means for forming the visible image on an image forming medium with a toner; and a plurality of transferring means for transfer the visible image onto the image transfer medium while bringing the visible image into contact with the image transfer medium. With respect to a toner amount which is transferred from each of the image forming medium onto the image transfer medium, difference between a toner deposition amount on the image transfer medium right after transferring the visible image from the image forming medium and a final toner deposition amount on the image transfer medium in the event of transfer of visible images is completed onto the image transfer medium is set such that the difference of the toner deposition amount of the visible image which is transferred by the transferring means disposed on an upstream side is larger than that on a downstream side in a direction where the visible image is successively formed.
