Patent ID: 8652731

Claim:
An electrostatic image developing toner comprising: (A) an amorphous polyester resin containing at least a repeating unit derived from a dicarboxylic acid component and a repeating unit derived from a dialcohol component represented by the following formula (1), and (B) an amorphous polyester resin differing in the weight average molecular weight from the amorphous polyester resin (A), wherein the difference (absolute value) in the weight average molecular weight between the amorphous polyester resin (A) and the amorphous polyester resin (B) is from about 30,000 to about 100,000: wherein each of R 1 and R 2 independently represents hydrogen or a methyl group, each of L 1 , L 2 and L 3 independently represents a divalent linking group selected from the group consisting of a carbonyl group, an ester group, an ether group, a sulfonyl group, a chain alkylene group which may have a substituent, a cyclic alkylene group which may have a substituent, an arylene group which may have a substituent, and a combination thereof, L 1 and L 2 , or L 1 and L 3 may form a ring, and each of A 1 and A 2 represents a rosin ester group.
