摘要

PROBLEM TO BE SOLVED: To provide a polyester resin for a toner that suppresses an incidence of offset in fixing.SOLUTION: The polyester resin for a toner comprises a repeating unit derived from a dicarboxylic acid and a repeating unit derived from dialcohol represented by general formula (1). In general formula (1), Rand Rrepresent hydrogen or a methyl group; L, Land Lrepresent a divalent connecting group selected from a group consisting of a carbonyl group, ester group, ether group, sulfonyl group, linear alkylene group, cyclic alkylene group, arylene group, and there combinations; and Aand Arepresent a rosin ester group derived from a disproportionated rosin or a rosin ester group derived from hydrogenated rosin. At least a part of Aand Apresent in a plurality of numbers is a rosin ester group derived from a disproportionated rosin and at least a part of Aand Ais a rosin ester group derived from a hydrogenated rosin.SELECTED DRAWING: None
