ABSTRACT:
A photosensitive material for use in electronic photography having a photosensitive layer principally comprises an amorphous selenium-arsenic alloy, the alloy having present therein crystalline arsenic trioxide in the form of arsenolite and claudetite. The charging ability of the photosensitive material is improved by controlling the ratio of relative absorbance peak intensity in the infrared spectrum of arsenolite to claudetite to be at least 0.5.
