Auger for magnetic materials with specific use for developer transport in elelctrographic printing systems

The invention relates generally to an electrophotographic printing machine and, more particularly, to a development system which includes a magnetic auger assembly, mounted in a housing, for mixing and transporting developer materials. A development system including a housing, a developer roll mounted in the housing, for depositing marking particles on an imaging surface having an electrostatic latent image thereon, an auger, for mixing and transporting the marking particles and carrier constituents of the developing material and; transferring mixed developer material to the developer roll, the auger comprising an elongate strip of magnetic material having a helix structure; a nonmagnetic sleeve enclosing the elongate strip of magnetic material; and means for rotating the elongate strip of magnetic material within the nonmagnetic sleeve, the elongate strip of magnetic material generates a magnetic field for transporting the developer material axially along an outer surface of the nonmagnetic sleeve when rotated by the rotating means.
