Title: Treatment of photoconductive cadmium sulfide
Inventor: HISAMURA MASABUMI
IPC: G03G5/08
Filed: 1983-02-24
Abstract: PURPOSE:To decrease stably the dependency of an image density on environmental temp. without complicating the process by subjecting photoconductive CdS powder to a heating treatment in the copresence of a specific amt. of activated carbon. CONSTITUTION:Photoconductive CdS powder is heated at 50-100 deg.C in the copresence of 1-50wt% activated carbon. There is no need for selecting particularly the kind of the activated carbon to be used in this heating and a desired result is obtd. by heating the powder in the copresence of the activated carbon for gaseous phase adsorption or desulfurization. The result is better as the change in the temp. in the stage of the heating is smaller but the change in the temp. hardly affects the characteristic if within the above-described temp. range. Even if the powder is heated, a phenomenon of a decrease in resistance is hardly observed if the heating is accomplished in the copresence of the activated carbon and the intrusion of impurities in the powder is obviated. The process is thus advantageous for production and is not complicated. The CdS having less dependency of an image density on environmental temp. when used for an electrophotographic sensitive body is stably obtd. by the above-mentioned treatment.
