Abstract

A method of producing an electrostatic developing material comprising mixing finely divided electrostatic printing powder material of an average particle size of less than about 30 microns, with a smaller proportion, based on the weight of said printing powder, of an additive. Stable, tough, virtually non-smudging polymeric with an average particle size of less than about the average particle size of said finely divided printing powder.
