Abstract

In an electrophotographic printing machine, developer material frequently com-prises toner particles adhering triboelectrically to carrier granules. Toner par-ticles are depleted from the developer material as successive electrostatic latent images are developed therewith. Additional toner particles are furnished from a hopper. Hereinbefore, these additional toner particles had been merely added to the hopper. It has been found that this operation frequently results in toner particles being spilled either exteriorly or interiorly of the printing machine and resulting in the operator being dirtied. In order to obviate these problems, a closed container having the requisite amount of toner particles therein is positioned by the operator in the toner hopper. The container is opened, and the toner particles automatically fed therefrom into the development system for use therein. After the toner particles are depleted from the container, the container is removed from the hopper and discarded. A new container is then inserted into the hopper containing a fresh supply of toner particles therein.
