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 includes: toner particles and organically treated alumina powder. The organically treated alumina powder has an X-ray diffraction characteristic showing a maximum X-ray intensity level I.sub.a-max and a minimum X-ray intensity level I.sub.a-min in a 2.theta. range of 20 to 70 degrees providing a ratio I.sub.a-max /I.sub.a-min of below 6. The alumina powder is amorphous or has a low-crystallinity of .gamma.-form, thereby showing a low agglomeratability to function as an effective flowability-improving agent for a toner. The structural water contained in the alumina powder contained favors hydrophobization treatment thereof and functions to suppress a charge-up phenomenon in a low humidity environment after the hydrophobization.
