A method for producing a liquid developer comprising a resin binder comprising a resin having an acidic group, a colorant, a basic dispersant, and an insulating liquid, wherein the method is selected from (a) a method comprising: step I: stirring raw materials comprising 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, and (b) a method comprising: step i: stirring raw materials comprising the resin binder and the basic dispersant at a temperature of equal to or higher than a glass transition temperature of the resin binder; 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; and step iii: mixing the dispersion obtained in the step ii with the colorant.
