摘要： A toner having a good chargeability stable against an environmental change is formed of toner particles each comprising at least a binder resin, a colorant, a release agent and a sulfur-containing polymer, and an external additive. The toner particles contain 100 to 30,000 ppm by weight thereof of at least one stabilizer element selected from the group consisting of magnesium, calcium, barium, zinc, aluminum and phosphorus. The toner particles may preferably be produced by suspension polymerization of a monomer composition containing the sulfur-containing polymer in an aqueous medium containing a dispersion stabilizer having the stabilizer element.

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.
