The present invention provides a toner for developing electrostatic image comprising a colored particle containing a binder resin, a colorant and a release agent, wherein the toner for developing electrostatic image has two or more maximum values of peaks or shoulders of loss tangent (tan δ) in the range from 50 to 120° C., a loss tangent (tan δ) in the range from 100 to 200° C. is 0.8 or less, and a dispersed diameter of the release agent is 0.1 times or less shorter than a volume average particle diameter of the colored particle.
