Abstract: For use in an electrophotographic copy machine utilizing magnetic brush roll development, an improved hollow magnetic roll made of non-magnetic material containing axially located grooves along the exterior periphery. The grooves are spaced in a range from 15-25 times the diameter of the permeable carrier beads used in the development process and the lands between grooves are polished to a high degree, e.g., 25 mu inches. The depth of the grooves is to a minimum of 1-2 times bead diameter while the groove width is to a minimum of 2-3 times bead diameter.

Abstract: An auger fed magnetic brush developer wherein two parallel augers continuously recirculate the developer mix and cause the mix to be enriched with toner prior to its being returned to the magnetic brush roll.
