Abstract
Magnetic toners, methods of their formation and utilization of the toners in various electrophotographic imaging systems is disclosed. The toners disclosed contain a nitrogen containing compound including, for example, amines and quaternary ammonium compounds. Toners containing such compounds are suitable for use in inductive development from a biased magnetic toner brush to an electrostatic image, and further subsequently such images may be transferred preferably by electrostatically type methods to a substrate such as plain bond paper.
