Abstract
A color image forming apparatus comprises developing units each of which contains a developer of each of three primary colors, and another developing unit containing a white developer. An image on the original is subjected to color separation to obtain image density data corresponding to each primary color, and when all the density data are lower than a predetermined value, the density data are multiplied by a predetermined ratio, and a predetermined density of a white image is set. Based on the multiplied data of each color a developed image corresponding to the image density data of each primary color is formed on a recording material, and a white image corresponding to the white color density data is on the same recording material, thereby reproducing clear pastel or halftone color images.
