Abstract
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.
