    Abstract: Provided is an electrostatic image developing toner including toner particles containing a light phase transition material that change from a solid state to a liquid state by light irradiation and a binder resin, wherein ΔH1 (J/g) is 0.1 or more, provided that ΔH1 (J/g) is an endothermic amount based on a melting peak derived from the light phase transition material in a first temperature raising process of raising a temperature from 25 to 200° C., the endothermic amount being obtained from a DSC curve measured by differential scanning calorimtry to the electrostatic image developing toner.

    Abstract: Provided is a compound that is fluidized by light irradiation and reversibly non-fluidized, is not significantly colored, and improves fixability and exhibits excellent image stability and color reproducibility when used for a toner.
    Provided is a compound represented by the following general formula (1), which is fluidized by light irradiation and reversibly non-fluidized: wherein
    Z1 and Z2 are CH or N, and Z1≠Z2;
    R1 is an aromatic hydrocarbon group having a substituent Ra selected from the group consisting of an alkyl group, an alkoxy group and a halogen atom at each of two ortho positions with respect to Z1; and
    R2 is a substituted or unsubstituted aromatic heterocyclic group.
