Abstract
A method of producing a photosensor having a photoconductive layer and a pair of electrodes provided through an ohmic contact layer on the same surface of the photoconductive layer for applying a voltage to the photoconductive layer. The method comprises the steps of: forming an insulating layer on one surface of the photoconductive layer except at portions where the pair of electrodes is to be formed; forming a layer of an ohmic contact layer forming material on the insulating layer; forming a layer of an electrode forming material on the layer of an ohmic contact layer forming material; and removing the electrode forming material except at the portions where the pair of electrodes is to be formed, and the ohmic contact layer forming material.
