摘要： A magenta toner for developing electrostatic images is formed of a binder resin, and a quinacridone pigment providing an X-ray diffraction spectrum showing two peaks in a Bragg angle (2.theta.) region of 5-10 deg. The magenta toner has an improved light fastness, may have a desired hue comparable to a printing process ink and is suitably used for electrophotographic full-color image formation. The magenta toner may preferably be formed through a process including a first kneading step starting from wet blending of a binder resin and two paste pigments including quinacridone and 2,9-dimethylquinacridone, respectively, under mild conditions not causing crystal transformation to form a master batch and a second kneading step of diluting the master batch together with other additive.

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.
