ABSTRACT:
A liquid developer for an electrostatic photography comprising a non-aqueous solvent whose electrical resistance is at least 10.sup.9 .OMEGA.cm and whose dielectric constant not more than 3.5 with a resin dispersed wherein the dispersed resin particles are copolymer resin particles obtained by a polymerization reaction, of a solution which contains a monofunctional monomer (A) which is soluble in the non-aqueous solvent but which is rendered insoluble by polymerization and a monofunctional macromonomer (B) whose number average molecular weight is not more that 10.sup.4 obtained by bonding a polymerizable double bond group;
to only one end of the main chain of a polymer
in the presence of a soluble resin for dispersion stabilization purposes obtained by bonding an acid group to just one end of at least the polymer main chain.
