PURPOSE:To obtain good images by performing electrolytic reaction by using the hydrogenated amorphous silicon of controlled electrical characteristics as a photosensitive layer. CONSTITUTION:A photosensitive layer substrate 21 made by depositing a hydrogenated amorphous silicon layer 12 on a conductive substrate 11 is put into electrolyte 23. For example, an aqueous soln. of zinc acetate of 0.01mol/l is used as the electrolyte. Next, a subject 26 is imaged on the photosensitive layer substrate 21 through a transparent wall 28 by a lamp 25 and a lens system 27. In this state, a constant voltage DC power source 29 is connected in a manner that a counter electrode 24 acts as anode and the conductive substrate 11 as cathode, and a voltage of about 5V is applied. Thence, according to the exposure, zinc will deposit on the surface of the layer 12. |
