PURPOSE:To obtain the titled body having good electrostatic characteristics and photosensitivity by incorporating a specific bisazo compd. composed of a fine particle having a prescribed particle size to the titled body as a carrier substance. CONSTITUTION:The bisazo compd. which has a structure shown by the formula, and a particle size smaller than one-fifth of the film thickness of the photosensitive layer and is composed of the fine particle of a brokened crystal is incorporated into a photosensitive layer of the titled body. In the formula, Ar1 and Ar2 are each a substd or unsatd. phenyl or napthyl group. The functional separating type photosensitive body is composed of the carrier generating layer and the carrier transfer layer formed on the conductive substrate. The carrier generating layer is formed by uniformly mixing the bisazo compd. which is finely pulverized by milling treatment with a suitable resinous binding agent and a solvent to form a coating solution and by coating the obtd. coating solution on a substrate followed by drying it. |
