Abstract
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 2.theta. is 14.degree.(.+-.0.3.degree.), and the half-width of the peak when the value of 2.theta. is 14.degree. (.+-.0.3.degree.) is 0.5 or more. This electrophotographic photoconductor has excellent qualities of low residual potential and stabilized quality.
