Abstract
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 de…
