PURPOSE:To render a photosensitive body to be formed on a conductive substrate high in photosensitivity, photosensitive in the longer wavelength region, and panchromatic by incorporating a perylene compd. in it. CONSTITUTION:A photosensitive layer 2a formed on a conductive substrate 1 contains a perylene compd. 3 for generating and transferring an electrostatic charge carrier necessary for photodecay, represented by a formula not shown here. The layer 2a is formed by coating the substrate 1 with a dispersion contg. this compd. dispersed into a binder soln. and drying it. A preferable thickness of the layer 2a is 3-50mum and a preferable content of the compd. 3 in the layer 2a is 10-70wt% of it. A metal, such as aluminum is vapor deposited to a plastic film, etc. are used for said substrate 1 of a photosensitive body, and all the insulating resin adhesive to the substrate can be used for the binder. Such a photosensitive body is high in photosensitivity in a longer wavelength region and panchromatic. |
