Abstract

The color printing system has two spaced photoconductive drums and a transfer roller positioned therebetween closely adjacent each one of the photoconductive drums. One of the photoconductive drums is arranged to have a black image developed thereon and one color image, e.g. yellow, developed thereon. The other photoconductive drum is arranged to have two color images, e.g. magenta and cyan, developed thereon. This is achieved by having two developer stations of the respective colors positioned adjacent each one of the photoconductive drums. A copy sheet is releasably secured to the transfer roller. The developed images from each of the photoconductive drums is transferred to the copy sheet in superimposed registration with one another to form a multicolor copy. The latent images may be recorded on each one of the photoconductive drums by either an optical system or a modulated laser beam. The system may also develop only one image or no images on either of the photoconductive drums depending upon the desired color of the copy.
