ABSTRACT:
An information image of a first original and an information image of a second original are synthesized on a photoconductor which includes a photoconductive layer having a spectral sensitivity to A-colored light but not having a spectral sensitivity to B-colored light, and a photoconductive layer having a spectral sensitivity to B-colored light, but not having a spectral sensitivity to A-colored light, which are formed in layers on a conductive base member, by taking the steps of charging the photoconductor to a predetermined polarity and then charging the photoconductor to reverse the original surface potential of the photoconductor, while retaining the charges applied to the photoconductor, to the extent that latent electrostatic images can be formed on the surface of the photoconductor, and exposing the photoconductor to an A-colored light image corresponding to the information image of the first original and a B-colored light image corresponding to the information image of the second originals simultaneously and or one after another to form the synthesized latent electrostatic images of the two originals on the photoconductor, and finally developing the synthesized latent electrostatic images by one or two types of developers.
