Color image forming apparatus having a transparent image forming body

Abstract

An image forming apparatus such as a copier or a printer for forming a color image. The image forming apparatus includes: a transparent photoreceptor drum for retaining a multi-color toner image in which the wall-thickness and an inner diameter of the drum are respectively between 2.5 mm and 8 mm and between 60 mm and 200 mm; plural chargers, provided on the periphery of the photoreceptor drum, for charging the drum surface; plural imagewise exposure systems, provided inside of the photoreceptor drum, for forming latent images on the drum surface; and plural developers, provided on the periphery of the photoreceptor drum, for developing the latent images with different color toners so as to form a superimposed multi-color toner image on the drum surface while the photoreceptor drum is being rotated one time.
