PURPOSE:To obtain a photosensitive material which is low in fogging density, is excellent in development progressing characteristic and is less increased in fogging by a temp. fluctuation by incorporating one kind among 3 kinds of specific compds. and specific compd. into an image receiving element. CONSTITUTION:At least one kind of the compd. selected from a chain thioether compd. (A1), cyclic compd. (A2) such as oxygen atom, -NR1 (R1 is a hydrogen atom or alkyl group), etc., and the compd. selected from the compd. (A3) expressed by formula I and the compd. expressed by formula II are incorporated into the image receiving element laminated on a photosensitive element. In formula II, Z<1> and Z<2> denote the aggregate of the atoms necessary for forming a 5- or 6-membered nitrogenous heerocycle. In formula II, X1 denotes a residual group of a development restrainer; L1 denotes a more coupler or divalent group; B denotes a ballast group. The photosensitive material which low in the fogging density, excellent in development progressing characteristic and is less increased in fogging arising from the temp. fluctuation is obtd. by constituting the material in such a manner. |
