PURPOSE:To obtain the titled body having an improved sensitivity and durability by providing a photosensitive layer contg. a specific bisazo compd. to the titled body. CONSTITUTION:The photosensitive layer contg. the bisazo compd. shown by the formula is provided to the photosensitive layer. Said photosensitive layer contains one or more kinds of the azo compds. shown by the formula. In the formula, A is a two valent aromatic hydrocarbon group or a two valent heterocyclic ring group contg. a nitrogen atom in the ring. As the two valent aromatic hydrocarbon group, one may use a two valent monocyclic aromatic hydrocarbon such as a 0-phenylene group, etc., and a two valent condensed polycyclic aromatic hydrocarbon group such as an 0-naphthylene group, a peri-naphthylene group, an 1,2-anthraquinonylene group and 9,10-phenathrylene group. Thus, the titled body has a high sensitivity and a good color sensitive property. When the titled body is used repeatedly, the titled body has an excellent sensitivity and a less change of the electrostatic chargeability. And the titled body having a less fatigue due to a light and an excellent durability is obtd. |
