Abstract

Apparatus for transporting particulate material between first and second zones separated by a dividing wall. A pair of cooperating rollers are sealingly located in an aperture in the wall and are rotated so that material coming into contact with either roll is transported through the nip between the rollers from the first to the second zone. In a particular embodiment, the rollers are located below a cleaning blade acting on a photoreceptor drum and toner dropping from the blade onto the lower roller which runs against the photo-receptor surface is fed into a toner collecting box. The arrangement permits the toner to build up in the toner box above the level of the toner entry point.
