Claim Text:
1. A method to produce toner comprising first aggregating at least one polyester latex, and at least one styrene acrylate latex, and optionally a wax dispersion, and optionally a pigment dispersion to form a core, wherein polyester latex particles are aggregated onto the core to form a shell, wherein the resulting aggregated particle is subjected to a continuous coalescence process, comprising: heating the aggregated particle to a first temperature beyond its glass transition temperature in a first heat exchanger to form a coalesced particles; quenching the coalesced particles to a second temperature below the glass transition temperature after a residence time; and recovering the quenched coalesced particles at an outlet; wherein the circularity of the aggregated particles is from about 0.900 to about 0.940, and the circularity of the particles in the coalesced particle slurry has increased to a value from about 0.940 to about 0.999; wherein the resulting toner comprises a hybrid composition with both styrene/acrylate and polyester.
