摘要： A magnetic brush development station for a reproduction apparatus. The magnetic brush development station includes a housing forming, at least in part, a reservoir for developer material. The reservoir has a pressure equalization seal. A mechanism is associated with the housing for readily moving the housing relative to the reproduction apparatus. Another mechanism selectively readily replenishes and/or empties at least one component of developer material with respect to the reservoir. A plurality of augers are located in the housing for mixing developer material within the reservoir. A drive for the augers, extending through the housing, has a seal therefor. A development roller, mounted within the housing, delivers developer material from the reservoir to a development zone. The development roller includes a core magnet inside a shell such that the core magnet and the shell having relative rotation. The core magnet extends less than the entire length of the development roller such that the developer nap on the shell does not extend to the end of the development roller. A metering skive, extending the length of the development roller, controls the quantity of developer material delivered from the reservoir portion of the housing to the development zone. The metering skive is positioned parallel to the longitudinal axis of the development roller at a location upstream in the direction of shell rotation prior to the development zone. Further, a magnetic seal is located in association with the skive at each end of the development roller. The magnetic field of the magnetic seal is sufficient to substantially prevent leakage of developer material from the ends of the development roller.

摘要： A magnetic brush development station with a housing forming a reservoir for developer material has a plurality of augers located in the housing for mixing developer material. A drive for the plurality of augers includes an assembly having a body extending through the development station housing. A plurality of bearings are positioned in the body with a spacer between the plurality of bearings. A rotatable shaft is connected between the plurality of augers and an auger drive member. A seal for the rotatable shaft has a lip formed of a material which is able to stretch sufficiently to maintain sealing contact with the shaft while the shaft is being rotated by the auger drive member.

摘要： A seal assembly for preventing developer material from damaging the drive shaft bearing in an electrographic reproduction apparatus development station. The development station has a housing defining internal chambers for particulate developer material, a rotatable mixer located in a developer material reservoir chamber within the housing, a developer device for applying developer material to an electrostatic image to be developed, a rotatable transporting mechanism for moving developer material from the reservoir chamber to the developer device, and at least one drive shaft, carried in a bearing supported by the development station housing, for rotating the rotatable mixer, the rotatable transporting mechanism, and the developer device. The seal assembly includes a plurality of seal members associated with the drive shaft and extending progressively outwardly, in the direction of the longitudinal axis of the drive shaft, from the developer material housing chambers of the development station toward the bearing. At least one of the seal members rotates with the drive shaft while adjacent seal members remain stationary.
