ABSTRACT:
A binder resin for an electrostatic image developing toner is obtained by polycondensation reaction of at least two polycarboxylic acids and at least one polyol, wherein the at least two polycarboxylic acids include at least one of a first specific polycarboxylic acid and a second specific polycarboxylic acid in an amount of from about 3 mol % to less than about 50 mol % based on a total amount of the at least two polycarboxylic acids, the binder resin includes a catalyst-derived metal in an amount of from about 0 ppm to about 10 ppm, and the binder resin has a glass transition temperature Tg of from about 45° C. to about 80° C.
