Abstract

In an electrophotographic printing machine, toner particles are employed to develop a latent image. After a period of time the toner particles are depleted from the developer material. In order to maintain a substantially uniform high quality copy, additional toner particles must be furnished to the developer material. As shown in Figure 1, toner dispenser 10 houses a supply of toner particles therein. A foam molded or formed belt 12 having pockets of a prescribed volume meter the required amount of toner particles from hopper 10 onto developer roller 16 mounted rotatably in housing 14.

REMOTE TONER DISPENSER (Cont'd)

An alternate embodiment for dispensing toner particles is shown in Figure 2. As depicted thereat, foam roller 18 meters toner particles from toner hopper 10 onto foam molded or formed belt 12. Belt 12 has pockets of a prescribed volume to meter toner particles onto developer roller 16 mounted rotatably in developer housing 14. In this way, the supply of toner particles within the developer material is maintained substantially constant optimizing development of the electrostatic latent image recorded on the photoconductive surface of the printing machine.
