PROBLEM TO BE SOLVED: To provide an image forming device capable of obtaining a graphic image with high resolution, obtaining a solid by pointed image with high density and obtaining an image where the graphic image and the solid image coexist in one image with high resolution and with sufficient density. SOLUTION: By rupturing the molecular structure of the component material of the charge generating layer 21 of a photoreceptive layer on the surface of the photoreceptor drum by photoirradiation and dispersedly forming a very small area(ruptured dot) A where potential is not attenuated to image exposure, the solid part of the latent image of the solid image is developed with high developing performance by utilizing an edge effect and the density of the solid image is sufficiently obtained even in developing contrast where the size of the developed dot is set as the proper size for the resolution of the image forming device. |
