PURPOSE:To improve the thermal developability and to obtain a high density image with little fog in a short time by incorporating a specified compd. into the photosensitive layer and/or the nonphotosensitive layer. CONSTITUTION:A compd. represented by formula I (where n=1 or 2, in case of n=1, R is 3-8C alkyl, alkenyl, alkoxy or alkenyloxy, and in case of n=2, R is 2-4C alkyl, alkoxy or 3-4C alkenyloxy) is incorporated into the photosensitive layer and/or the nonphotosensitive layer of a photosensitive material. The compd. may be further incorporated into an image receiving member. The photosensitive layer is composed of photosensitive silver halide, a reducing agent, a binder and the compd. represented by the formula I and it is preferable that the photosensitive layer further contains a dye providing substance, especially a dye providing substance which releases or forms a diffusive dye and an org. silver salt. The dye providing substance may double as a reducing agent. |
