(57) [Problem] To provide a toner for developing an electrostatic image, which has sufficient blocking resistance, high-temperature offset resistance and coloring power. SOLUTION: In the electrostatic image developing toner containing at least a binder resin, a colorant, a polar resin and a release agent, When the polar resin is synthesized by at least a polyfunctional alcohol component, and the number average molecular weight of the polar resin by GPC is Mn and the weight average molecular weight is Mw, Mw / Mn Has a value of 3.0 <Mw / Mn ≦ 6.0. |
