Developer units, electrophotograhic apparatuses, and methods of supplying developer material to photoconductive members in electrophotographic apparatuses are disclosed. An embodiment of the developer units for supplying a developer material to a photoconductive member, comprises 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; a second auger disposed below the first auger; a first trim blade disposed at a first angular position about the outer surface of the magnetic roll, the first trim blade adapter for leveling the developer material on the outer surface during rotation of the magnetic roll; and a second trim blade disposed at a second angular position about the outer surface of the magnetic roll, the second trim blade adapted for leveling the developer material on the outer surface that has been leveled by the first trim blade during rotation of the magnetic roll; wherein the magnetic roll is rotatable to supply the developer material that has been leveled by the second trim blade to the photoconductive member.
