In electrophotographic printing machines, toner dispensing systems are generally faced with the problem of maintaining a smooth even flow of toner particles from a toner bottle through a hopper to the dispensing system. As shown in the drawing, toner dispenser 10 includes a container 12 which normally stores a supply of toner particles. Container 12 is inverted and mounted on housing 14 of dispenser 10. Seal 16 insures that there is no leakage of toner particles from dispenser 10. After the container has been positioned on housing 14, agitator 18 is rotated in the direction of arrows 20 to fluff the toner particles in container 12. An auger 22 is located in the lower portion of housing 14 to advance the toner particles therefrom to the developer housing. In this way, the toner particles replenish those particles utilized by the development system to form copies.
