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.

Abstract: This invention is directed to an improved process for developing electrostatic latent images comprising (1) providing a development zone situated between an imaging member and a transporting member, comprised of a stationary shell containing rotating magnets therein, (2) transporting synthetic developer composition into the development zone by causing rotation of the magnets in the stationary shell, (3) effecting movement of the imaging member in a direction opposite to the direction of movement of the rotating magnets, wherein the developer composition is desirably agitated in the development zone by magnetic means, and wherein developer particles are available immediately adjacent the imaging member; the developer particles comprised of toner resin particles and carrier particles comprised of resin particles and magnetite; with the distance between the imaging member and stationary shell being from about 0.1 millimeter to about 1.5 millimeters.
