摘要： A toner and a two-component developer for developing electrostatic images are disclosed. The toner comprises toner particles and the two-component developer comprises the toner and a carrier. The toner particle has a two-layer structure of a core layer and a surface layer, produced by suspension polymerization. The core layer and surface layer are mainly comprised of a resin having a low softening point and a resin having a high softening point, respectively. In the surface layer, a polyester resin having a specific acid value and a specific molecular weight is included to impart an appropriate water absorption to the toner. Due to the appropriate water absorption and superior fluidity, the toner can achieve a speedy rise of charge to give electrostatic charges in a stable quantity over a long period of time, and it can give a high image density and images with superior fine-line reproduction and highlight reproduction.

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.
