PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner containing a binder resin and a colorant and having good fixing properties over a wide temperature range. SOLUTION: The electrostatic charge image developing toner contains at least a binder resin, a colorant and a release agent, wherein an exothermic peak temperature of the release agent based on a differential scanning calorimeter is at 60-100°C, and when the amount of heat absorbed per unit weight of the release agent at the temperature lower than a glass transition on-set temperature of the binder resin based on the differential scanning calorimeter is represented by a, the total amount of heat absorbed per unit weight of the release agent by b, and the average particle diameter of the toner by c (μm), the expression: 0.05≤a/(b×c)≤0.6 is satisfied.
