Abstract

In the development system of an electrophotographic printing machine, it is frequently necessary to provide additional toner particles to the developer mixture. This may be achieved by housing a supply of toner particles 10 in hopper 12. A foam roller 14 mounted rotatably in the aperture of hopper 12 meters the desired quantity of toner particles therefrom. As the particles descend, brush 16 rotates to break up agglomerates of toner. A flicker bar 18 prevents toner particles from accumulating on brush 16. Toner particles are discharged into sump 20 for mixing with the developer material contained therein.
