Patent ID: 6991884

Claim:
Chemically prepared toner for electrophotographic printers, consisting essentially of agglomerated polymeric dispersant stabilized pigment particles, a fuser release agent, a charge control agent dispersion, and a self-stabilized essentially surfactant free latex binder, wherein the polymeric dispersant includes at least two segments, a hydrophilic polymeric segment and a protective colloid or reactive surfactant segment, the polymeric dispersant having a weight average molecular weight ranging from about 5,000 to about 30,000 as determined by gel permeation chromatography and a hydrophobicity ranging from about 10 to about 90 percent by weight, wherein the chemically prepared toner includes agglomerated toner particles having a unimodal particle size distribution with a number average particle size (N) ranging from about 5.0 to about 8.5 microns, a volume average particle size (V) ranging from about 5.0 to about 8.5 microns, and wherein V minus N (V-N) ranges from about 0 to about 1.5.
