摘要： Disclosed is a process for producing a liquid developer for electrostatic photography which comprises a highly insulating hydrocarbon medium and resin particles dispersed therein, said process comprising polymerizing a monomer (A) soluble in said medium, but insolubilized upon being polymerized in the presence of a polymer (S) insoluble in said medium and having a carboxyl group, a hydroxyl group or an amide group. In this process, a monomer (B) soluble in said medium and still soluble upon being polymerization and/or a monomer (C) having at least two polymerizable unsaturated double bonds may also be polyumerized.
