Abstract

A one-shot color image forming system for producing a color image with one exposure, characterized in that three kinds of color toners capable of transmitting cyan, magenta and yellow therethrough, respectively and adapted to develop colors identical with those of the transmitted light are used, and red, green and blue light, the quantities of exposure light energy of which can be varied, being applied to the color toners on a photosensitive member to vary the combination of the light of these colors and the quantity of exposure light energy in order to selectively remove the color toners from the photosensitive member.
