ABSTRACT:
A toner process comprising mixing a colorant dispersion with a latex, a wax dispersion, and a coagulant, and wherein the latex contains a polymer with a static yield stress of from about 0.05 to about 3 dyne/cm2, a viscosity for the polymer latex of from about 5 to about 35 centipoises (cps), and wherein said toner product possesses a volume average particle size distribution index GSDv of equal to or less than about 1.27, a number average particle size distribution index GSDn of equal to or less than about 1.30, a low number average particle size index GSDn50/16of equal to about or less than about 1.32, and a ratio of the volume average particle size distribution index GSDv to a number average particle size distribution index GSDn of from about 0.93 to about 1.
