An apparatus for color electrophotography including optical scanning means which moves intermediate a stationary original document and a copy sheet for scanning the colored image on the document onto, and a drum-shaped photoreceptor which is rotated in synchronism with the scanning movement of said scanning means. Successive images are scanned through different color filters to form successive electrostatic latent images thereon which are successively transferred from the rotating photoreceptor onto a stationary copy sheet. Each electrostatic image is successively developed using developer of a color corresponding to that of the filter used during the preceding scan before the following scan.
