PURPOSE:To obtain an electrophotographic sensitive body having characteristics high in sensitivity to light in a long wavelength region by forming a photosensitive layer having an azulenium salt compd. represented by a specified formula on a conductive substrate. CONSTITUTION:The azulenium salt compd. is represented by general formula I, II, or III in which R1-R5 are each H, halogen, or a univalent org. residue; X is an atomic group necessary to form an optionally substd. 5-, 6-, or 7-membered aromatic ring; A is a bivalent org. group combined through a double bond; and Z<-> is an anion residue. Said compd. is vapor deposited or dissolved or dispersed in a proper binder and a photoconductive film contg. it is formed to obtain an electrophotographic sensitive body. |
