ABSTRACT:
In a target structure for use in a photoconductive image pickup tube, a P-type photoconductive film is deposited on an N-type transparent conductive film which is deposited on a transparent substrate. The P-type photosensitive film comprises first and second photoconductive substances. The commencement of the deposition of the first photoconductive substance is delayed a predetermined time from that of the second photoconductive substance thereby forming a film of the first photoconductive substance which is not contiguous to the junction surface between the N-type transparent conductive film and the P-type photoconductive film.
