Abstract

An electrostatographic toner material may be provided from a heterogeneous agglomeration of a low melting temperature monomer or polymer and a relatively higher melting tempera-~ ture monomer or polymer with a colorant. The low melting temperature monomer or polymer has a melting temperature of from about 60°C to about 120°C, and the higher melting temperature monomer or polymer has a melting temperature of from about 135°C to about 200°C. The lower melting temperature monomer or polymer is preferably bound in a matrix of the higher melting temperature monomer or po1y~ mer. The lower melting temperature material is preferably polyethylene and the higher melting temperature material is preferably styrene, The toner material may be fine1y-~ divided into particles having an average diameter of from 5 to 20 microns and mixed with carrier particles to form a developer mixture.
