Abstract:
The present disclosure relates to chemically processed toner. The toner may be prepared by an emulsion aggregation method by forming a polyester dispersion wherein the polyester has an acid value of about 5 to about 50 and a particle size of about 50 to about 500 nanometers. The polyester dispersion may then be combined with a pigment and/or release agent dispersion wherein the pigment and/or release agent dispersion may contain a dispersant. This may then be followed by heating and recovering agglomerated toner particles wherein the toner particles may have a mean particle size of about 3 to about 15 microns and an average degree of circularity of between about 0.90 to about 1.0.
