ABSTRACT:
Described is a process for the treatment of certain toner materials, useful in electrophotographic development, which process in one embodiment involves subjecting an electrically conductive toner material to an attrition process, thus causing the removal to a small portion of the surface of the toner while at the same time exposing the underlying inner portion. By preparing toners in accordance with this process the fusing temperature of the toner is lowered by at least 10.degree. F., thereby resulting in better fixing of the toner and higher quality images when such a toner is used as a developer.
