    摘要： A toner for developing an electrostatic image is formed from toner particles containing a binder resin, a colorant, and a charge-controlling agent. The charge-controlling agent comprises an aromatic oxycarboxylic acid, a metal compound of the aromatic oxycarboxylic acid, and an inorganic compound formed from an inorganic anion and an inorganic cation. The aromatic oxycarboxylic acid, the metal compound of the aromatic carboxylic acid and the inorganic anion are contained in proportions of A (wt. %), B (wt. %) and C (ppm), respectively, satisfying the following conditions: 1/99.ltoreq.A/B.ltoreq.20/80, and 10.sup.2 .ltoreq.C. Because of the inclusion of an inorganic compound providing a sufficient amount of inorganic anion, the charge-controlling agent shows a stable charge-controlling characteristic, and the resultant toner exhibits a stable developing performance and transferability in continuous image formation in various environmental conditions.
