Abstract
A process for producing a resin particle liquid dispersion for an electrostatic image developing toner, the process comprising: polycondensing a polycondensable monomer by utilizing an acid having a surface activating effect as a polycondensation catalyst, so as to obtain a polycondensed resin; and dispersing the polycondensed resin in an aqueous medium to which a base is added, so as to obtain a resin particle liquid dispersion in which a median diameter of resin particles is from 0.05 to 2.0 μm, or the process comprising: polycondensing a polycondensable monomer by utilizing an acid having a surface activating effect as a polycondensation catalyst in a co-presence of a polycondensed resin, so as to obtain a polycondensed resin-containing material; and dispersing the polycondensed resin-containing material in an aqueous medium, so as to obtain a resin particle liquid dispersion in which a median diameter of resin particles is from 0.05 to 2.0 μm.
