Patent ID: 7294442

Claim:
A toner for developing an electrostatic image, comprising: a first resin; and a colorant, which is prepared by (1) dissolving or dispersing the colorant and the first resin in an organic solvent to prepare a toner constituent liquid; and (2) mixing the toner constituent liquid with an aqueous medium that includes fine particles of a second resin, and at least an agent selected from the group consisting of a dispersant, an emulsifying agent, and a surfactant, wherein the toner satisfies the following relationship: 3 ≦G=R−R ideal ≦20, wherein G represents a ratio of a weight of components other than the colorant and the first resin that are included in the toner and are insoluble in the organic solvent, to a total weight of the toner, R represents a weight ratio of insoluble components included in the toner, which are insoluble in the organic solvent, to the total weight of the toner, and R ideal represents an ideal weight ratio of the colorant and the first resin and is determined from a formula of the toner.
