ABSTRACT:
The image forming process of the present invention includes subjecting a photosensitive material having at least one dye-forming layer for each of the three primary colors on a support to scanning exposure using light sources modulated in accordance with the image data, thereby reproducing a full color image of quality in which delicate shades in a high density color developed portion of high purity are reproduced stably. For the exposure dynamic range of the photosensitive material that the density of color generation of one dye-forming layer exhibiting the highest sensitivity to the light beam from at least one light source varies beyond the visual threshold with respect to a change of a modulation control minimum unit in the exposure quantity of said at least one light source, said one dye-forming layer is color generated by exposure to the light beam from another light source to which another dye-forming layer exhibits the highest sensitivity such that a variation of the color generation density of said one dye-forming layer may be below said visual threshold.
