摘要： A toner for developing electrostatic images is formed of toner particles comprising (a) a binder resin, (b) a colorant or magnetic material, (c) an aromatic hydroxycarboxylic acid (A), and (d) a metal compound of the aromatic hydroxycarboxylic acid (A). The aromatic hydroxycarboxylic acid (A) and the metal compound of the aromatic hydroxycarboxylic acid (A) are contained in a weight ratio of 1:99 to 10:90. As a result of co-inclusion of a small amount of the aromatic hydroxycarboxylic acid (A) in addition to the metal compound thereof, the resultant toner is provided with a quick chargeability in a low humidity environment and an improved level of triboelectric charge in a high humidity environment, presumably because of the stabilization effect of the small amount of the aromatic hydroxycarboxylic acid (A) on the metal compound thereof.

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.
