PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which has a stable fixing behavior in a wide temperature region and an offset resistance and is suitable for a heat roll system making it possible to perform printing with a high grade and high accuracy. SOLUTION: The electrostatic charge image developing toner contains a binder resin, coloring matter, and a releasing agent and. The binder resin is a polyester resin prepared by reacting (A) a polybasic acid compound selected from bivalent or higher valence polybasic acids and/or acid anhydride and/or their lower alkyl ester and (B) bivalent or higher valence aliphatic polyhydric alcohol as main components, and the releasing agent is a compound prepared by reacting one or more compounds selected from alcohol or amine having a long chain alkyl group or alcohol or amine having a fluoroalkyl group, unsaturated polyvalent carboxylic acid and/or its acid anhydride and synthetic hydrocarbon wax.
