ABSTRACT:
A method of making toner particles, includes: mixing a latex emulsion, a colorant emulsion, an optional was emulsion, and optional additives in a first reactor to form a slurry; discharging the slurry from the first reactor to a second reactor through a homogenizer; heating the slurry in the second reactor to form aggregated particles in said slurry; discharging the aggregated particles and slurry from the second reactor to a third reactor; heating the aggregated particles and slurry in the third reactor to coalesce the aggregated particles into toner particles; discharging the toner particles and slurry from the third reactor to a fourth reactor; cooling the toner particles; optionally classifying said toner particles to remove coarse particles; and optionally washing and drying said toner particles, wherein the first reactor, second reactor, third reactor, and fourth reactor are at least two different reactors.
