Abstract

Disclosed is a proposed method for removing trace organic contaminants from aluminum photoreceptor drum substrates. By placing the photoreceptor in a quartz housing and irradiating with 185-254 nm UV light in the presence of oxygen organic contaminants are oxidized by ozone generated in situ. The method may also result in the formation of an acceptable aluminum oxide blocking layer of desired thickness on the surface of the aluminum drum substrate. The method provides photoreceptor aluminum drum substrates which are free of organic contaminants and have aluminum oxide blocking layers with improved thickness and uniformity compared to substrates prepared by conventional methods.
