PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that has excellent low-temperature fixability, ensures separability in fixing, and suppresses the occurrence of UFP and the occurrence of unevenness in glossiness.SOLUTION: When the melting peak temperature derived from a crystalline polyester resin in the course of increasing a temperature in differential scanning calorimetry of a toner for electrostatic charge image development is Tmc(°C), the melting peak temperature derived from a mold release agent is Tmw(°C), and the glass transition point of the toner is Tg(°C), the following formula (1) is satisfied. When the melting peak temperature derived from the crystalline polyester resin, Tmc(°C) is 60 to 95°C, and the mold release agent is made of a hydrocarbon wax, the melting peak temperature derived from the mold release agent, Tmw is 75 to 95°C, and when the mold release agent is made of an ester wax, Tmw is 60 to 80°C. Formula (1): Tg<Tmw≤Tmc. |
