Abstract
A continuous flow process for producing coalesced toner particles from aggregated toner particles includes continuously flowing a slurry of aggregated toner particles having a size of from about 5 microns to about 7 microns through one or more heat exchangers, wherein a residence time in the one or more heat exchangers is from about 1 second to about 15 minutes, thereby producing coalesced toner particles having a circularity of from about 0.930 to about 0.990. The aggregated toner particles comprise a polymer resin, a colorant, an aggregating agent, and an optional wax.
