Abstract

An apparatus in which a latent image is developed with marking particles. In one mode of operation, the marking particles advance to the latent image. In another mode of operation, the marking particles are diverted from the latent image to prevent development thereof. A system of this type is particularly useful in color electrophotographic printing wherein successive electrostatic latent images are developed with different color marking particles.
