Abstract

In an electrophotographic printing machine, the developer mix comprises carrier granules and toner particles. The toner particles are employed to develop the latent image recorded on a photoconductive surface, However, in operation, additional toner particles must be furnished to developer mix to maintain the concentration thereof substantially constant. Metering cups 14 have an aperture 16 therein adapted to dispense toner particles 12 from chamber 18. As cartridge 10 rotates, metering cups 14 are aligned so that the gravitational force causes toner particles 12 to pass through aperture 16 and in a downwardly direction through metering cup 14 into the developer mix. A plurality of metering cups 14 may be disposed about the periphery of cartridge 10,
