ABSTRACT:
To remove ferromagnetic carrier beads from the surface of a photoreceptor leaving a development station in an electrophotographic machine, the carrier beads are magnetically attracted to the surfaced of an elongated, rotating cylinder. The cylinder surface is provided with a raised spiral thread to create a material conveying auger operating to axially convey the attracted beads to a cylinder end portion beyond a side edge of the photoreceptor, where the carrier beads fall into a sump.
