PURPOSE:To stably obtain a polymerized image high in contrast by using a combination of specified compounds as photosensitive and heat-developable elements. CONSTITUTION:This photosensitive body comprising the photosensitive and heat-developable elements and a polymerizable element contains as the photosensitive and heat-developable elements, silver halide, an organic silver salt, as a reducing agent a compound represented formula I, as a development promoter a compound represented by formula II, and in formulae I and II, each of R<1> and R<2> is H, halogen, or the like; m is 1, 2, or 3; A is a bonding group having a valence of 1, 2, or 3; and each of r<1> and r<2> is H, alkyl, or the like, thus; permitting a polymerized image high in contrast to be stably obtained. |
