摘要： The object of the present invention is to provide a toner having a uniform composition of toner materials among toner particles, excelling in charge stability, enabling high-quality images without substantially causing fog and toner scattering, and having a small diameter and a narrow particle size distribution. The present invention also provides an effective production method of the toner, and an image forming method and the like using the toner. For this end, the present invention provides a method for producing a toner in which a dissolved and dispersed solution of toner materials is dispersed as dispersion particles in an aqueous medium containing no organic resin fine particles to prepare an oil droplet-in-water dispersion, and organic resin fine particles are added to the oil droplet-in-water dispersion to thereby granulate a toner in the presence of the organic resin fine particles.
