PURPOSE:To enhance sensitivity to rays in a long wavelength region by using a photoconductive film contg. a specified azulenium salt compd. for a photosensitive body. CONSTITUTION:The photosensitive body uses the photoconductive film contg. an azulenium salt compd. represented by the formula in which each of R1-R7 is H, halogen, or a univalent org. residue, and at least one combination among the combination of R1 and R2, R2 and R3, R3 and R4, R4 and R5, R5 and R6, R6 and R7 may form a condensed ring; R8, R9 are each alkyl, aryl, aralkyl, or they may form a ring together with N; Ar1 and Ar2 are each arylene; and Z<-1> is an anion. The photoconductive film contg. such an azulenium salt compd. is formed on the conductive substrate by the vacuum deposition method or by dispersing it into a binder and coating with this dispersion, or the like method, and the use of such an azulenium salt compd. for the photosensitive body permits electrophotographic characteristics high in sensitivity to be obtd., especially, to laser beams having oscillated wavelength in the longer wavelength region.
