ABSTRACT:
An apparatus for forming multi color toner images includes a photoreceptor drum which has an opening at a first end through which an inside of the photoreceptor drum is accessible, and which has an outer surface on which multi color toner images are formed. A supporting member is provided which is capable of being inserted into the inside of the photoreceptor drum through the opening thereof. A cover member is provided on a first end of the supporting member for covering the opening. A plurality of exposing devices are mounted on the supporting member so that the plurality of exposing devices and the supporting member are incorporated inside the photoreceptor drum when the cover member is fixed so as to cover the opening. A plurality of charging devices are provided around the outer surface of the photoreceptor drum for charging the outer surface of the photoreceptor drum. The plurality of exposing devices conduct imagewise exposing inside the photoreceptor drum so as to form a plurality of latent images for plural different colors on the charged outer surface of the photoreceptor drum, and a plurality of developing devices are provided around the outer surface of the photoreceptor drum for developing the plurality of latent images with plural different color toners so that multi color toner images are formed on the outer surface of the photoreceptor drum.
