摘要:
An electrophotographic photoreceptor comprising an electrically conductive substrate having thereon a photosensitive layer is disclosed, wherein the photosensitive layer contains, as a charge generating material, a dispersion of selenium or a selenium alloy and at least one squarylium compound represented by formula (I): ##STR1## wherein A represents a fluorine atom, a hydrogen atom or a hydroxyl group, with B representing a hydroxyl group; or A represents a hydrogen atom or a fluorine atom, with B representing a methyl group, in the same binder resin. The electrophotographic photoreceptor not only has broad spectral sensitivity from the visible to infrared region but is excellent in other electrophotographic properties.
