A toner supply and dispensing cartridge for use with a xerographic copying machine. The cartridge includes a cylinder which contains a supply of particulate toner material, the cylinder having a plurality of toner dispensing ports formed along the longitudinal axis of the cylinder. The cylinder is supported for rotation at both ends and includes a freely riding multi-cup scoop extending the length of the cylinder and disposed inside for dispensing the toner material, said scoop preferably having an approximately cross-shaped cross-section. Preferably, at least part of the cartridge is formed of a transparent or translucent material so that the level of toner material remaining inside may be easily determined.
