| PURPOSE: To obtain an organic photoelectric converting element of excellent responding speed and SN ratio (Photoelectric current/Dark current) characteristic, by adding donor divinylbenzene compound to azo dye. CONSTITUTION: A photoconductor contains effective elements divinylbenzene compound as expressed by the formula and the specified azo dye. The weight mixing ratio of the employed azo dye, divinylbenzene compound and insulating resin is; azo dye/insulating resin: 1/3W3/1, divinylbenzene compound/insulating resin: 1/3W1/1. An excessive mixing ratio of azo dye, divinylbenzene compound to insulating resin causes poor adherence of photoconductor film with electrode and insulating substrate and poor reliability. further, shorter ratio causes excessively low photoconductive coefficient σp and the SN ratio (σp/σd) can not be raised. A preferable range of thicknesses of the photoconductor film is 0.2W2μm. COPYRIGHT: (C)1986,JPO&Japio | ||||||
