ABSTRACT:
An electrophotographic printing machine in which successive colored filtered light images expose a photoconductive member recording successive charge patterns thereon. Each charge pattern is developed with single color magnetic particles forming successive single color powder images on the photoconductive member. These single color powder images are transferred, in superimposed registration, to a sheet of support material. The superimposed powder images are permanently affixed to the sheet of support material producing a colored copy of the original document being reproduced by the electrophotographic printing machine.
