PURPOSE:To enhance photosensitivity characteristics and photoconductive sensitivity in the wavelength region of semiconductor laser beams by incorporating a specified naphthalocyanine compound in a photosensitive layer. CONSTITUTION:The photosensitive layer formed on a conductive substrate contains as the organic photoconductor one of the naphthalocyanine compounds represented by formulae I and II in which M is one of elements in the groups Ia, IIa, and IIIa of the periodic table or a transition metal atom; each of R<1> and R<2> is H, F, Cl, Br, OH, nitro, straight or branched alkyl, aryl, or aralkyl, optionally substituted by halogen, or polyether; m is a number of R<1> and an integer of 0 - 5; n is a number of R<2> and an integer of 0 - 4; and each of Y and Z is -O- or -NH-, thus permitting the obtained photosensitive body to be superior in photosensitive characteristics and sufficient in photoconductive sensitivity to semiconductor laser beams. |
