Abstract
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.
