Patent ID: 8486596

Claim:
A toner, produced by a method comprising: dissolving or dispersing toner components comprising a colorant and at least one of a the binder resin and a precursor thereof in the organic solvent to prepare a toner components liquid; dispersing the toner components liquid in an aqueous medium including a surfactant, a particulate resin A having the same polarity as the surfactant and a volume average particle diameter of from 5 to 25 nm, and a particulate resin B having a volume average particle diameter of from 10 to 500 nm to form liquid droplets, wherein the average particle diameter of particulate resin A is smaller than the average particle diameter of particulate resin B; and removing the organic solvent from the liquid droplets, wherein the binder resin comprises a polyester resin; wherein the particulate resin A comprises a vinyl resin; and wherein the particulate resin B comprises fine particles of a cross-linked resin comprising at least one of a styrene polymer, an acrylate polymer, and a methacrylate polymer, wherein the particulate resin B is incompatible with the binder resin and is swellable in an organic solvent, wherein the particulate resins A and B adhere to a surface of the toner, wherein when the particulate resin B is dropped into a 30-ml screw vial using a measuring pipette to have a depth of 20 mm from the bottom of the screw vial, 10 ml of ethyl acetate are further added thereto using a measuring pipette, and the screw vial is left for 24 hours so that a mixture of the particulate resin B and the ethyl acetate is phase-separated into a whitish particulate resin B dispersion phase on a lower side and an ethyl acetate phase on an upper side, a height of the whitish particulate resin B dispersion phase from the bottom of the screw vial is 21 mm or more.
