ABSTRACT:
A method for forming toner particles includes polymerizing monomers to form a latex comprising polymer particles; combining the latex with unsaturated curable resin to form aggregates containing the polymer particles and the unsaturated curable resin particles; and heating the aggregates to form coalesced particles. A toner composition that may be formed by the process described herein contains toner particles containing polymer containing photoinitiator and unsaturated curable resin. Another toner composition that may be formed by the process described herein contains toner particles containing unsaturated curable resin and, on the surface of the toner particles, photoinitiator.
