PURPOSE:To obtain good-quality copied images for a long period of time without generating image deterioration such as image blurring with an image base laminated with a photoconductive substrate, photoconductive layer and insulating layer having color sepn. filters by applying a stabilizer for stabilizing characteristics to the insulating layer. CONSTITUTION:The stabilizer for stabilizing the characteristics is applied onto the insulating layer 4 of the image base 1 laminated with the photoconductive substrate 2, the photoconductive layer, and the insulating layer 4 having the color sepn. filters 4a. Application of the stabilizer on the insulating layer is executed by interposing a compd. layer contg. a group I noble metal or alloy or noble metal element of periodic table between the insulating layer and the photoconductive layer and previously depositing the noble metal or alloy on the insulating layer by electroplating, vapor depositing, welding or adhering in the form of powder. An org. acid salt of the noble metal element is mainly used as the compd. contg. the noble metal element. Said compd. is coated in the form of powder or soln. by a sponge roll or the like on the front face of a photosensitive body or the front or rear face of the insulating layer to form a thin layer of the powder or uniform compd. thereon. The insulating layer is thereafter fixed. The characteristics are thereby stabilized. |
