摘要:
A chemically prepared toner for electrophotographic printers and method therefor using a unique polymeric dispersant. The chemically prepared toner includes agglomerated polymeric dispersant stabilized pigment particles, a fuser release agent, a charge control agent dispersion, and a self-stabilized essentially surfactant free latex binder. The polymeric dispersant includes at least three segments, a hydrophilic polymeric segment, a hydrophobic polymeric segment, and a protective colloid or reactive surfactant segment. The weight average molecular weight range of the dispersant ranges from about 5,000 to about 30,000, and a hydrophobicity ranging from about 10 to about 90 percent by weight. The chemically prepared toner includes agglomerated toner particles have a unimodal particles size distribution with a number average particle size (N) ranging from about 5.0 to about 8.5 microns and a volume average particle size (V) ranging from about 5.0 to about 8.5 microns.
