Title: Electrophotographic device
Inventor: YAMAZAKI MUTSUKI
IPC: G03G5/082
Filed: 1984-09-21
Abstract: PURPOSE:To obtain a sharp image by laminating a photoconductive layer on a conductive base which has lead sulfide laminated on the surface and thus forming a photosensitive body, and using coherent light which is larger than a specific value as a light source. CONSTITUTION:An Al base 10 is fitted as the conductive base in an ordinary bell jar opposite to a boat for heat vapor deposition in parallel. Then, the bell jar is evacuated to a specific degree of vacuum and held at specific temperature, and lead sulfide 11 is laminated by heat vapor deposition. At this time, O2 is admitted and vapor deposition is carried out in an oxygen atmosphere where the degree of vacuum is lowered to a specific value. Then, the layer contains a small amount of lead oxide and becomes a P type semiconductor to form a Schottky barrier by joining with the Al substrate 10. Therefore, electrons are prevented from being implanted into a photosensitive layer from the substrate 10 to obtain both functions of reflection prevention and charge impantation prevention. Further, coherent light of >=600nm is used as the light source and then the coherent light transmitted through the photoconductive layer is absorbed by lead sulfide to prevent reflection from the substrate; even when the coherent light is used as the light source, there is no interference with incident light and an image has no fringe.
