PURPOSE:To prevent the adverse influence of the occurrence of base soiling, etc., at the time of toner development, while the advantage of high sensitivity is maintained by providing a photoconductive layer on a photosensitive layer via a transparent sheet. CONSTITUTION:An image forming material where the photoconductive layer is provided on the photosensitive layer whose solubility is changed by an exposure via the transparent sheet is used, and electrifying and exposing to the photoconductive layer are carried out. After the toner development is carried out, the photosensitive layer is exposed by a full surface exposure, the transparent sheet is peeled, and the photosensitive layer is developed to form a relief image. As a photosensitive composition material constituting the photosensitive layer, a composition material used for a PS-plate, a wipon liquid, a photoresist sensitized liquid, etc., can be used, and as a photoconductive compound, a phthalocyanine compound, especially, an epsilon-type copper phthalocyanine compound can be used. |
