ABSTRACT:
An apparatus which develops an electrostatic latent image recorded on a photoconductive member with toner. Fluidized toner is transported from one end of the developer housing to the other end. A donor roller, spaced from the photoconductive member is adapted to receive toner and transport the toner to a development zone adjacent the photoconductive member. The excess toner is contained and diverted from the ends of the donor roller into the chamber of the housing. This insures that excess toner does not build-up on the sides of the donor roller resulting in the sides of the copy being background free.
