ABSTRACT:
A device for replenishing the developer material in a copying machine comprises a supply reservoir with a roller, preferably having a flocculent surface, acting as a bottom closure therefor, the roller being driven from a shaft associated with developer conveyor means of the developing unit. Each movement step of the roller is a consequence of a revolution of the shaft. A ratchet and pawl mechanism, preferably controlled by a solenoid, links the shaft and roller. The device may also include adjustable timing means which ensures that a preset developer replenishment is always effected even if the copying machine stops.
