ABSTRACT:
A toner including a binder resin comprising a polyester resin in an amount of from 50 to 100% by weight, wherein the polyester resin includes an unsaturated polyester resin which is preferably a crystalline polyester resin; a colorant; and a fatty acid metal salt which is preferably microencapsulated. A method for preparing a toner including forming particles of a toner composition including at least a binder resin including a polyester resin in an amount of from 50 to 100% by weight and a colorant, in an aqueous medium to prepare a dispersion of a particulate material, wherein the polyester resin includes an unsaturated polyester resin; drying the particulate material; and mixing a fatty acid metal salt with the particulate material to subject double bonds of the unsaturated polyester resin to oxidation polymerization.
