    摘要： The electrophotographic photoconductor of the present invention includes a conductive substrate and a photosensitive layer containing perylene pigment as a charge generating material formed on the conductive substrate. The X-ray diffraction peak of the perylene pigment exhibits its peak when the value of 2ϑ is 14°(±0.3°), and the half-width of the peak when the value of 2ϑ is 14° (±0.3°) is 0.5 or more. This electrophotographic photoconductor has excellent qualities of low residual potential and stabilized quality.
