PURPOSE:To enhance sensitivity and durability of a sensitive body by incorporating a specified bisazo pigment layer as a photoconductor. CONSTITUTION:The photosensitive layer formed on a conductive substrate contains as a photoconductor the bisazo compound represented by the formula shown on the right in which X is O or dicyanomethylene; Y is H, alkyl, halogen, or the like; and A is a divalent aromatic hydrocarbon group or N-containing heterocyclic group. The photosensitive layer containing this compound may have a single-layer structure or the functionally separated laminate structure, but the latter is preferred from the viewpoints of sensitivity and residual potential. The use of this structure permits the photosensitive body superior in sensitivity and durability to be obtained. |
