ABSTRACT:
Substantial amounts of non-magnetic (zinc stearate) particles are removed from a supply of single component magnetic toner descending from a toner hopper before the toner reaches the image drum of an ion deposition printer. Such separation is accomplished by providing an unwanted particle chamber extending along substantially the entire width of the toner unit housing adjacent and generally below the toner hopper outlet. A blower is effective through an air manifold assembly mounted on the toner unit housing to draw the unwanted particles from such chamber.
