Patent ID: 7560213

Claim:
A resin particle liquid dispersion for an electrostatic image developing toner, comprising: a dispersion medium; and a resin particle containing at least a polyester dispersed in the dispersion medium, wherein the polyester comprises a terminal addition-polymerized polyester having an acid value of from about 5 to about 70 mg·KOH/g, and the terminal addition-polymerized polyester is obtained by a process comprising: polycondensing a polycondensable monomer having a composition comprising: (a) at least one of a polyvalent acid monomer having no addition-polymerizable unsaturated group and a derivative of the polyvalent acid monomer having no addition-polymerizable unsaturated group in an amount of from about 10 to about 80 mol % based on all monomers; (b) a polyhydric alcohol monomer having no addition-polymerizable unsaturated group in an amount of from about 10 to about 80 mol % based on all monomers; and (c) at least one of a monomer having a carboxyl group and an addition-polymerizable unsaturated group and a derivative of the monomer having a carboxyl group and an addition-polymerizable unsaturated group in an amount of from about 0.5 to about 20 mol % based on all monomers, to obtain a polyester having an addition-polymerizable unsaturated group at a terminal; and addition-polymerizing the addition-polymerizable unsaturated group of the polyester having an addition-polymerizable unsaturated group at a terminal.
