Abstract
A developer station for use in an electrographic copier utilizing moving discrete dielectric sheets, such sheets being adapted to respectively carry latent image charge patterns and travel along a path in pattern-developing relation to such station. The developer station includes a housing forming a reservoir for developer material. The housing has an opening in juxtaposition with the travel path. Developer material is transported from the reservoir through such opening and into such travel path. A movable shielding belt blocks the opening to prevent developer material from reaching the travel path. In response to approach of a discrete dielectric sheet moving along the travel path toward the station, the belt is moved to a position where a window through the belt overlies the opening thereby unblocking such opening to enable transported developer material to contact a discrete dielectric sheet when such sheet is in pattern-developing relation to the developer station.
