ABSTRACT:
A reproduction apparatus utilizing clear marking particles in the development of an image, the clear marking particles being laid down so as to prevent offset upon fusing of an image to a receiver member. The reproduction apparatus is disclosed as including a dielectric member adapted to have latent images formed thereon. A development station, is provided including a plurality of developer units respectively containing marking particles of different colors, at least one developer unit containing black marking particles and another developer unit containing clear marking particles. The development station selectively develops latent images with marking particles from the developer units respectively. A transfer station serves to transfer developed marking particle images to a receiver member, and a fuser assembly fuses a marking particle image on a receiver member. The developing station is controlled such that the developer unit for applying clear marking particles is selectively activated to apply clear marking particles to a receiver member, the clear marking particles uniformly decreasing toward the edges of the receiver member.
