Abstract

In electrophotographic printing machines, it is desirable to automatically reclaim toner particles and return the same to the development system for subsequent recycling. To avoid degradation of copy quality, it is necessary to insure that the reclaimed toner is free from contaminants, such as paper fibers, kaolin particles and the like. It has been found that these contaminants carry a "wrong sign" charge and, hence, transport toner particles which develop out in background regions.
