Production of electrophotographic sensitive body

Abstract

Abstract PURPOSE:To enable production of a photosensitive body having a uniform density distribution, an increase in electrifying potential and a decrease in the variance thereof by supplying gradually a material for vacuum deposition to an evaporating source and forming instantaneously the film thereof. CONSTITUTION:Powder SeTe is weighed into a powder supply device 14 and an evaporating source 12 is electrically heated after evacuation to form an electric charge transfer layer 21 on a conductive substrate 11. An evaporating source 13 is then electrically heated to >=400 deg.C prescribed temp. and thereafter the function to supply the powder is started to conduct the powder by a guide 15 to the source 13 and to supply continuously by each small amt. to said source so that the supplied powder is nearly instantaneously evaporated without forming a molten pool in the evaporating source, thus forming an electric charge generating layer 22. If the density distribution of the Te compsn. of a photosensitive body 2 obtd. in such a way is analyzed from the surface to the inside of the photosensitive layer, the resultant film is remarkably improved not only on the compsn. deviation of the Te density with respect to the base material but also in the variance among samples.
