Abstract: A conveyor assembly for xerographic reproducing machines. The conveyor assembly includes a plurality of elongated buckets mounted at their opposite ends to endless belts. The belts are each mounted on upper and lower pulleys mounted on shafts. The lowermost shaft is an idler while the uppermost shaft is power driven to move the buckets in a continuous path of movement from a developer sump portion whereat two-component developer is picked up by the buckets to above the upper pulleys. There the buckets are inverted by their movement to dump the conveyed developer to an input chute leading to the upper end of a cascade development zone. A closed cell polyurethane foam roller of a diameter substantially equal to that of the upper pulleys is mounted therebetween for rotation therewith whereby developer being spilled by the buckets may be directed to the input chute.
