Liquid developer for electrostatic charge image

A liquid developer for electrostatic charge images comprising a polymer selected from (a) a polymer containing at least one polymerizable monomer represented by the following general formula (1) as a component of the polymer, and (b) a polymer containing at least one polymerizable monomer represented by the following general formula (2) and chloromethylstyrene as copolymer components, the polymer being dispersed in a carrier liquid having an electric resistance of at least 10.sup.9 .OMEGA..cm and a dielectric constant of at most 3, ##STR8## wherein R.sub.1 and R.sub.2, which may be the same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, an aralkyl group or a heterocyclic group, said R.sub.1 and R.sub.2 may form a ring with the nitrogen atom, said ring may contain carbon, oxygen, nitrogen or sulfur as a constituent element, the sum of the carbon atom numbers of R.sub.1 and R.sub.2 is at most 36;

• and n represents a positive integer of 1 to 6, ##STR9## wherein A represents a hydrogen atom or a methyl group and B represents a group shown by the following general formula (3), (4), (5), (6) or (7), ##STR10## wherein R.sub.1 and R.sub.2 have the same significance as defined in general formula (1), and said R.sub.1 and R.sub.2 may form a ring with the nitrogen atom shown in each of general formulae (3), (4), (5), (6) and (7), and the ring may contain carbon, oxygen, nitrogen, or sulfur as a constituent element.
