Abstract

In an electro photographic process utilizing a two-component developer, migration of carrier beads out of the developer station due to mechanical and/or electrostatic action creates undesirable machine contamination and/or copy quality defects. A simple, low-cost, self-cleaning scavenger device is described which overcomes some of the disadvantages of a scavenger magnetic roll and/or a fixed scavenger magnetic bar. The device (Fig. 1A,B,C) consists of an assembly 10 which, in the rest position of Fig. 1A, is placed in close juxtaposition to the surface of photoconductor (PC) 11 which carries undesirable carrier beads (Image Omitted) 13.
