PROBLEM TO BE SOLVED: To provide a toner and a toner resin excellent in the balance between low-temperature fixability and grindability and excellent in gloss after fixing in an electrostatic charge image developing toner for a heat fixing system. In a polyester resin for toner obtained by polycondensation of a polyol component and a polycarboxylic acid component, the polyol component has a molar average cohesive energy of 7.0 × 10 4 to 1.4 × 10 5 J, and 150 A polyester resin for toner comprising 20 to 100% by weight of one or more polyester resins (A1) having a storage elastic modulus at 2.5 ° C. of 2.5 × 10 3 Pa to 5 × 10 6 Pa.
