Claim Text:
1. A continuous process for rounding conventional toner particles comprising; forming a conventional toner particle slurry by mixing a dispersant and/or a liquid with dry toner particles; heating, in a first heat exchanger, the conventional toner particle slurry to a first temperature beyond its glass transition temperature to form a coalesced toner particle slurry; quenching the coalesced toner particle slurry to a second temperature below the glass transition temperature after a residence time; and recovering the quenched particle slurry at an outlet, wherein the circularity of the conventional toner particles in the quenched toner particle slurry is from approximately 0.940 to 0.999 and the time frame for the heating, quenching and recovering steps is less than 20 minutes.
