description A method for producing a liquid developer containing a resin binder containing a resin having an acidic group, a colorant, a basic dispersant, and an insulating liquid, including: step I: stirring raw materials containing the resin binder, the colorant, and the basic dispersant at a temperature of equal to or higher than a glass transition temperature of the resin binder; and step II: adding dropwise from 50 to 500 parts by mass of the insulating liquid to a stirred mixture of the step I, based on 100 parts by mass of the stirred mixture at a temperature of equal to or higher than a glass transition temperature of the resin binder, thereby carrying out a phase inversion emulsification, to provide a dispersion of toner particles. The liquid developer obtainable by the method of the present invention is suitably used in development or the like of latent images formed in, for example, electrophotography, electrostatic recording method, electrostatic printing method or the like.
