Flexible multi-layer photoreceptor of electrophotography

摘要

A photoreceptor of electrophotography having a flexibility and a sensitivity to electromagnetic wavelengths of a wide range extending as far as the red color region of the spectrum of light rays is produced by forming a layer of a halogen-doped Se-S alloy on a substrate and further forming on said layer a halogen-doped Se-Te alloy layer. The Se-S alloy contains sulfur in a weight ratio of 0.1 to 0.35 to the Se-S alloy. The Se-Te alloy contains tellurium in a weight ratio of 0.05 to 0.35 to the Se-Te alloy.
