Claims

[Claims for Utility Model Registration] 1. A photoconductor, a means for uniformly charging the photoconductor, and an electrostatic latent image formed by scanning and exposing the photoconductor with a light output controlled by multicolor image information. and a first developing device that develops the electrostatic latent image with a first color colored fine powder toner to form a first color toner image on the photoreceptor, each having a different hue of colored fine powder toner. a developing means equipped with developing devices for n-1 (n≧2) hues, a means for mounting and conveying the recording medium, and a means for bringing the recording medium into contact with the photoreceptor only during the transfer process; It has a transfer belt means for transferring the toner image onto the recording medium, a cleaning means for removing the toner image remaining on the photoreceptor after the transfer process, and a control means for controlling the same. In a color image electrophotographic apparatus in which exposure and development steps are repeated n times to form toner images of n colors on a photoconductor, and the color toner images are transferred and recorded onto a recording medium using a transfer belt means, the toner image remaining on the photoconductor is A color image electrophotographic apparatus characterized in that the color image is removed by the cleaning means and the transfer belt means. 2. The color image electrophotographic apparatus according to claim 1, wherein when the cleaning means and the transfer belt means remove the toner image remaining on the photosensitive belt, a transfer electric field is applied to the transfer belt.
