PROBLEM TO BE SOLVED: To provide a toner that has excellent printing durability, and suppresses leakage of toner and blowoff of toner after being left unused in a high-temperature environment.SOLUTION: A toner for electrostatic charge image development contains colored resin particles containing a binder resin and colorant, and an external additive, and has a value of CI (compression index) of 1.5 to 3.2, the value of CI (EAC/BFE) being a ratio of a value of EAC (total energy after compression) obtained by a compression test using a powder fluidity analyzer, to a value of BFE (basic fluid energy) obtained by a stability test using the powder fluidity analyzer. |
