发明名称 ELECTROPHOTOGRAPHIC SENSITIVE BODY
摘要 PURPOSE:To charge electrostatically a sensitive body to proper potential in the dark, to reduce the scattering of charges in the dark, to scatter rapidly charges when light is irradiated, and to improve the mechanical characteristics by forming a photosensitive layer contg. a carbazole deriv. represented by a specified general formula. CONSTITUTION:This sensitive body has a photosensitive layer 2 contg. at least one of carbazole derivs. represented by general formulae I , II on an electrically conductive support 1. In the formulae, each of R1 and R2 is H, alkyl, cyano or the like, each of R3 and R4 is alkyl or aralkyl, each of R5 and R6 is alkyl, aralkyl or a hetero atom forming a heterocyclic ring, and (n) is 1 or 2. Compounds represented by formulae III, IV are examples of the carbazole derivs. represented by the formulae I , II, respectively. Since the carbazole derivs. cause hardly absorption in the visible light region, a sensitizing dye such as triarylmethane or pyrylium is added. The amount of the carbazole deriv. contained in the photosensitive layer 2 is 30-70wt%, and that of the sensitizing dye is 0.1-5wt%.
