Abstract
Within the sump of a dry developing, magnetic brush system in an office copier machine, twisted strips of aluminum sheet metal are used to form an auger blade mixing arrangement for the purpose of mixing dual component developer. Each auger blade is formed from strip sheet metal into a single, elongated helical convolution and is appropriately journaled at each end for the application of rotative power. In addition, the auger blades have smooth, rounded, axial edges which provides extended useful life to the carrier constituent due to reduced shearing effects.
