Abstract
A color process in which color copies of an original document containing color information are reproduced. Successive single color electrostatic latent images are developed with particles having a predetermined triboelectric charge thereon. These particles are transferred from the single color electrostatic latent images to a sheet of support material in a prescribed sequence. The sequence of transfer is such that each successive layer of toner particles transferred to the sheet of support material has a lesser triboelectric charge thereon than the preceeding layer transferred thereto. In this manner, back transfer from the sheet of support material to the electrostatic latent image is minimized.
