摘要

PROBLEM TO BE SOLVED: To provide a toner for electrostatic charge image development that suppresses the occurrence of image defects even after being exposed to high temperature and high humidity for a long time.SOLUTION: A toner for electrostatic charge image contains toner base particles containing colorant, a binder resin, and a mold release agent; and an external additive subjected to a hydrophobic treatment. The external additive contains inorganic particles having a saturated fatty acid, preferably a saturated fatty acid having a melting point of below 20°C on the surface thereof. The saturated fatty acid is preferably a methyl branched saturated fatty acid.
