Abstract

In electrostatographic printing machines, toner is typically replaced in the development system by being supplied to the system from a toner container such as a bottle on a continuing basis. One conventional way of doing this is to provide a disposable toner bottle of generally circular cross section which contains an internal wire auger to move toner horizontally toward the dis ensing opening and out of the bottle. In such practice one of the

A further difficulty frequently encountered is that significant quantities of toner clumps can remain in the bottle and not be dispersed by the auger.
