Patent ID: 8883387

Claim:
An electrostatic image developing toner comprising: an amorphous first polyester resin that is a polycondensation product of at least a carboxylic acid component and a rosin-containing alcohol component represented by the following formula (1): where in the formula (1), each of R 1 and R 2 independently represents a hydrogen atom 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 chained 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 independently represents a rosin ester group; and a second polyester resin having a difference (absolute value) in parameter of solubility relative to the first polyester resin of from about 0.3 (cal/cm 3 ) 1/2 to about 3 (cal/cm 3 ) 1/2 .
