    摘要： The present invention provides a toner which is obtained by dissolving and/or dispersing in an organic solvent a toner material that includes at least a functional group-containing modified polyester resin capable of undergoing an elongation reaction and/or a crosslinking reaction with an active hydrogen group-containing compound, a vinyl resin, a releasing agent, and a colorant to prepare a toner solution, then emulsifying and/or dispersing the toner solution in an aqueous medium to prepare an emulsified dispersion, and allowing the functional group-containing modified polyester resin to undergo an elongation reaction and/or a crosslinking reaction with the active hydrogen group-containing compound in the aqueous medium, wherein the vinyl resin is concentrated near the surface of the toner.
