Abstract
A xerographic reproduction device with a reusable, closed-loop, belt photoconductor, having the photoconductor supported by at least one roller whose surface is axially grooved. These grooves are dimensioned to accept and hold carrier beads at or below the surface of the roller. As carrier beads accumulate in a groove, they move longitudinally of the roller, to accept more beads. The beads thereby move to the end of the roller and are discharged, preferably to a bead-capturing device.
