ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE PROVIDED WITH SUCH ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND ELECTROPHOTOGRAPHIC DEVICE

摘要

An electrophotographic device wherein light having a short wavelength (380nm-500nm) is used as image exposure light and an electrophotographic photoreceptor having excellent photoelectric conversion efficiency for such wavelength as a whole is used. The electrophotographic photoreceptor is composed of a reflection layer, a charge generating layer and a charge transporting layer formed on a supporting body. The total reflectance and regular reflectance of the short wavelength light of the reflection layer are 30% or more (to the standard white board) and less than 15%, respectively. The absorbance of the short wavelength light of the charge generating layer is 1.0 or less.
