Abstract: A method of forming toner particles includes aggregating a mixture of a latex, a wax, and an optional pigment to form pre-toner particles, and coalescing the pre-toner particles at a substantially constant target temperature selected within a range from about the glass transition temperature of the pre-toner particles to about 75° C., thereby creating toner particles having a substantially constant particle size distribution during the coalescing step.

Abstract: A method for preparing toner particles is disclosed. In embodiments, a suitable method includes aggregating a mixture comprising at least one resin, an optional pigment and an optional wax to form aggregated particles, freezing aggregation of particles by adjusting the pH of the aggregated particles to a freezing aggregation pH; coalescing the aggregated particles to form toner particles at a first pH that is higher than the freezing aggregation pH; and recovering the toner particles.
