Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a polyester resin for toner by which the polyester resin can be efficiently mass-produced with stable quality without using bisphenol A or its derivative as an alcohol component. SOLUTION: The polyester resin is synthesized in which acid components are (1) disproportioned rosin and (2) terephthalic acid and/or isophthalic acid, alcohol components are (3) glycidyl ester and (4) an aliphatic diol, a crosslinking component consists of a polycarboxylic acid and/or a polyol, a molar ratio between the acid components (1)/(2) is 0.2-0.6, and a molar ratio between the alcohol components (3)/(4) is 0.05-0.4. The polyester resin is discharged from a reactor vessel under conditions of 160-250°C, a viscosity of 3-400 Pa s at the start of discharge and a viscosity of 50-500 Pa s at an end, and after cooling and pulverization, the resulting pulverized powder is mixed using a mixer and made uniform.

Abstract: A polyester resin for a toner, which is produced by using (1) a disproportionated rosin and (2) terephthalic acid and/or isophthalic acid, as an acid component, (3) a glycidyl ester of a tertiary fatty acid and (4) an aliphatic diol having two to ten carbon atoms, as an alcohol component, and a three or more-valent polycarboxylic acid and/or a three or more-valent polyol, as a crosslinking component, wherein the mole ratio of the acid component (1) to the acid component (2) [(1)/(2)] is 0. 2 to 0.6, and the mole ratio of the alcohol component (3) to the acid component (4) [(3)/(4)] is 0.05 to 0.4; a toner for developing an electrostatic charge image which comprises the polyester resin for a toner (a binding resin), a coloring agent and a charge controlling agent; and a method for forming an image using the a toner for developing an electrostatic charge image.
