Abstract

PURPOSE:To obtain a receptor having high sensitivity in a region ranging from visible light to near infrared light and superior charging characteristics by vacuum- depositing copper phthalocyanine on an electrically conductive substrate to form a charge generating layer and laying a charge transferring layer on the generating layer. CONSTITUTION:Copper phthalocyanine is vacuum-deposited on an electrically conductive substrate 1 in 0.1-10mum thickness and heat treated at 180-280 deg.C to form a charge generating layer 2 having high sensitivity in a region ranging from visible light to near infrared light. On the layer 2 a charge transferring layer 3 is formed by dispersing an inorg. charge transferring material such as Se or an org. charge transferring material such as carbazole in a single substance or a binder. Thus, a receptor with high sensitivity, high charging receptivity and high cycle stability is obtd.
