Apparatus for developing a latent image

Abstract

An apparatus for developing a latent image recorded on an imaging surface, including a housing defining a chamber storing a supply of toner; a donor member, spaced from the imaging surface, for transporting developer material on the surface thereof to a region opposed from the imaging surface, a transport member for transporting toner from said housing and loading toner onto the donor member, the transport member, further includes a mask layer adjacent to the photoconductive layer, the mask layer having a screen pattern; a charging device for charging the photoconductive layer and an exposure device for discharging unmasked portions of the transport member thereby generating the fringe field on the surface of the transport member to attract toner from the housing to the surface of the transport member.

Dependencies are inferred from the claim text.
