PROBLEM TO BE SOLVED: To provide an electrostatic charge image developer capable of suppressing toner leakage due to continuous printing, while maintaining excellent low-temperature fixability, and having excellent printing durability and thin line reproducibility during the continuous printing.SOLUTION: An electrostatic charge image developer contains colored resin particles including a binder resin, a colorant, and a charge control agent, and an external additive. The electrostatic charge image developer contains, as the external additive, spherical inorganic fine particles A having a number average primary particle diameter of 36 to 300 nm and a sphericity of 1.00 to 1.20, and acicular zinc oxide fine particles having an average major diameter of 200 to 1,500 nm and an aspect ratio of 3 to 20. |
