ABSTRACT:
When superimposing toner images of a plurality of colors on an image supporting member to form a color image, a free phase ion in a precedent image is removed without distorting the toner image precedently formed on the image supporting member, thereby improving reproducibility of image dots of the toner images having second and subsequent colors to obtain a high-definition color image with high contrast.
