PROBLEM TO BE SOLVED: To provide a toner for a liquid developer having a small particle diameter and excellent in dispersion stability in an insulating liquid.;SOLUTION: A method of manufacturing the toner includes: preparing an emulsion liquid containing an aqueous dispersion medium and, dispersed therein, dispersoids containing a resin material which has an acidic group having a salt structure formed with a basic substance and has an acid value of 5.0-20 mgKOH/mg when it is in a form of an acidic substance without forming a salt with the basic substance, a colorant and an organic solvent; coalescing the dispersoids contained in the emulsion liquid to obtain coalescent particles; removing the organic solvent contained in the coalescent particles to obtain colored resin particles; washing the colored resin particles with an aqueous liquid; dispersing the washed colored resin particles in an aqueous liquid and performing an acid treatment to obtain an acidic dispersion liquid having a pH adjusted to 3.0-6.0; washing the colored resin particles subjected to the acid treatment with an aqueous liquid; and drying the washed colored resin particles.;COPYRIGHT: (C)2010,JPO&INPIT
