发明名称 METAL COMPLEX PIGMENT-CONTAINING TONER FOR ELECTROPHOTOGRAPHY AND METHOD FOR PRODUCING THE SAME
摘要 Disclosed is a metal complex pigment-containing toner, wherein a pigment dispersion index (A) determined as a standard deviation of an X-ray fluorescence intensity, per unit area of toner particle surface, of a central metal of the metal complex pigment contained in the toner is less than 2 [cps/(KeV·mum2)], and a pigment surface dispersion index (B) obtained by dividing an average value of the X-ray fluorescence intensity by an X-ray fluorescence intensity of the central metal of the metal complex pigment in the entire composition of the toner as measured by an X-ray fluorescence analysis for analyzing deep internal regions is more than 0.027 [cps/(KeV·mum2·kcps)]. In this toner, the pigment is moderately dispersed on the surface side of the toner particles uniformly at a high concentration, and therefore, the coloring power thereof is improved.
