Abstract: Provided is a method for producing an electrostatic image developing toner comprising: agglutinating wax and resin particles in aqueous medium; manufacturing a toner composed of wax and resin for developing an electrostatic image, wherein the wax is inside colorants. The method solves the problems of existing toner for developing an electrostatic image, such as low dispersion and easy detachment of colorants, low image density, the contamination of carriers and developing sleeves and low durability. The toner of the invention has high roll viscosity resistance and durability, and the colorants will not detach.
