Claim Text:
1. A method of making a toner for use in electrophotographic printing, comprising: (a) dispersing pigment particles, acrylic monomer, acidic monomer, an initiator, and optionally a charge control agent together in a first solvent so as to create a dispersion; (b) activating the initiator; and (c) conducting polymerization of the acrylic monomer and the acidic monomer to form a polymer, where the polymer precipitates out of solution to create a polymer coating on the pigment particles, wherein each pigment particle is at least substantially covered by the polymer coating, the polymer coating is non-crosslinked and has a Tg of from about 20° C. to about 160° C., and each pigment particle is uniformly chargeable over its entire surface.
