摘要

PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that has excellent low-temperature fixability and suppresses the occurrence of image defects.SOLUTION: There is provided a toner for electrostatic charge image development that contains, as a binder resin, at least a resin including an amorphous polyester resin, crystalline polyester resin, and a structural unit derived from a styrene compound, where the proportion of the crystalline polyester resin relative to the total of the amorphous polyester resin and the crystalline polyester resin is 12 mass% or more and 40 mass% or less; the storage elastic modulus G' becomes 1.0×10Pa at temperatures of 30°C or more and 45°C or less; at a temperature X'°C at which the ratio of the storage elastic modulus G' at a temperature X°C after two-hour storage at a temperature X°C (after heat storage) to the storage elastic modulus G' at a temperature X°C before storage at a temperature X°C (before heat storage) [storage elastic modulus G' (after heat storage)/storage elastic modulus G' (before heat storage)] becomes maximum, the ratio [storage elastic modulus G' (after heat storage)/storage elastic modulus G' (before heat storage)] is 3 or more and 50 or less.SELECTED DRAWING: None
