    摘要: A process for preparing a toner includes forming an emulsion with a buffer solution and an amorphous biodegradable polyester resin represented by Formula (1): wherein each n independently represents an integer of 1 to about 20 and x and y represent respective ratios of respective monomeric units and x ranges from about 0 to about 1000 and y ranges from about 0 to about 300; adding a colorant, a coagulant, and optionally a wax to the emulsion to form a mixture; heating the mixture, permitting aggregation and coalescence of the mixture to form toner particles; and recovering the toner particles.

    摘要: A process for preparing a toner, includes solvent flashing wax and resin together to emulsify the resin and wax to a sub-micro size; mixing the wax and resin emulsion with a colorant, and optionally a coagulant to form a mixture; heating the mixture at a temperature below a glass transition temperature of the resin to aggregate the resin, colorant, and wax, to form aggregated particles; heating the aggregated particles and coalescent agent at a temperature above the glass transition temperature of said resin, to coalesce the aggregated particles to form toner particles, optionally cooling the mixture; and isolating the toner particles.
