PURPOSE:To enhance sensitivity and durability of a sensitive body by incorporating a specified bisazo pigment in a photosensitive 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 A is a divalent aromatic hydrocarbon 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 high sensitivity and low residual potential, and either of the charge generating layer or a charge transfer layer may be overlaid on the other layer, and an adhesive layer may be inserted between both the layers. The use of this compound permits the photosensitive body superior in sensitivity and durability to be obtained. |
