Patent ID: 7881639

Claim:
A developer unit for supplying a developer material to a photoconductive member, comprising: a magnetic roll having an outer surface; a first auger adjacent the magnetic roll, the first auger being rotatable to convey the developer material to the outer surface of the magnetic roll, the first auger being partially immersed in a first supply of the developer material; a second auger disposed below the first auger, the second auger being partially immersed in a second supply of the developer material; a first trim blade disposed at a first angular position about the outer surface of the magnetic roll, the first trim blade being adapted for leveling the developer material on the outer surface during rotation of the magnetic roll and configured to remove developer material from the outer surface of the magnetic roll and direct the removed developer material into the first supply and second supply of the developer material; and a second trim blade disposed at a second angular position about the outer surface of the magnetic roll, the second trim blade being adapted for further leveling the developer material on the outer surface that has been leveled by the first trim blade during rotation of the magnetic roll and configured to remove developer material from the outer surface of the magnetic roll and direct the removed developer material into the second supply of the developer material; wherein the magnetic roll is rotatable to supply the developer material that has been leveled by the second trim blade to the photoconductive member.
