ABSTRACT:
Disclosed is a method for producing a resin dispersion type electrophotographic liquid developer containing resin particles dispersed in a high insulation hydrocarbon medium which comprises, in the presence of a first polymer dissolved in said medium which is soluble in said medium and has a polar functional group having adsorptivity to a second polymer, polymerizing a monomer having a polar functional group having adsorptivity to said first polymer to produce the second polymer which is low in solubility in said medium and is substantially particle.
