A magnetic brush development station for a reproduction apparatus has 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 dielectric support member in a development zone; a transport mechanism for transporting developer material from the reservoir to the developer roller; a metering skive for establishing a developer material metering gap; 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 at the metering gap between the metering skive and the developer roller can be substantially prevented. A method of removing a skive blockage from a metering skive in a magnetic brush developer station is also disclosed.
