ABSTRACT:
An electrophotographic photoreceptor is disclosed, which comprises an electrically conductive substrate having thereon a photosensitive layer comprising a resin binder in which the following two kinds of charge generating materials are dispersed: (i) selenium or an alloy of selenium and (ii) a phthalocyanine derivative represented by the formula: ##STR1## wherein M represents AlCl, Mg, VO, InCl or H.sub.2. The electrophotographic photoreceptor exhibits a broad spectral sensitivity extending from the visible to the infrared regions of the spectrum and, therefore, can be suited for printers which utilize such light sources as semiconductor lasers, light emitting diodes, etc.
