PURPOSE:To obtain a photosensitive body having high sensitivity and satisfactorily stable repeatability by laminating an electric charge generating layer contg. a benzopyrylium salt of trimethine structure and bromated poly-N-vinyl carbazole and electric charge transfer layer contg. a poly-N-vinyl carbazole on a conductive substrate. CONSTITUTION:The charge generating layer is constituted of the benzopyrylium salt of trimethine structure expressed by constitutional formula I and the bromated poly-N-vinyl carbazole. R1 in constitutional formula is hydrogen or phenyl group, R2 is hydrogen, p-methoxyphenyl group, 4'-methoxynaphthyl group or 2'-methoxynaphthyl 1' group, R3 is a methoxy group, nitro group, phenyl group, R4 is hydrogen, methoxy group, X is oxygen or sulfur atom. The bromated poly-N-vinyl carbazole is substd. with 0.5-2 bromines per carbazole ring. The poly-N-vinyl carbazole is incorporated into the charge transfer layer and these layers are laminated and deposited on an Al substrate or the like. |
