Patent ID: 7953352

Claim:
A magnetic brush development station for a reproduction apparatus, said magnetic brush development station comprising: a housing forming, at least in part, a reservoir for developer material; a developer roller mounted within the housing for delivering developer material to a reproduction apparatus dielectric support member in a development zone, the developer roller including a core magnet inside a shell, the core magnet and the shell having relative rotation; a transport mechanism for transporting developer material from the reservoir to the developer roller; a metering skive for establishing a developer material metering gap between the metering skive and the developer roller for controlling the quantity of developer material transported from the reservoir portion of the housing to the developer roller and then through the development zone to develop a latent image charge pattern on the dielectric support member; and a mechanism for selectively moving the metering skive to an operative position relative to the developer roller and to a position remote from the developer roller, wherein a build up of contamination collected at the metering gap between the metering skive and the developer roller when the metering skive is at the operative position can pass through the gap.
