Abstract

A color image forming apparatus such as a printer or a copier. The apparatus includes: a photoreceptor, having a transparent body, for forming a toner image; a charger for charging the photoreceptor; a LED array, accommodated inside the photoreceptor, for imagewisely exposing the photoreceptor with exposure light so as to form a latent image on the photoreceptor; a developer for developing the latent image with toner so as to form a toner image on the photoreceptor; in which a process of forming the toner image is repeated for plural times so that plural toner images are superimposed to from a composite toner image; a transferor for transferring the composite toner image onto a recording medium; and a photodetector, accommodated inside the photoreceptor, for detecting light from the photoreceptor in which the light has a high transmission factor for the photoreceptor.
