Abstract

A photoconductive composition which exhibits excellent dark reduction retention, excellent sensitivity to radiation from the near infrared region to the infrared region as well as excellent long-term stability, is comprised of an inorganic photoconductor, a cyclic acid anhydride and a spectral sensitizing dye dispersed in a binding resin. A laser beam scanning exposure can be performed on said composition to produce electrophotographic images.
