ABSTRACT:
A photosensitive material comprises a photosensitive composition comprising a photosensitive and heat-developable element and a photopolymerizable element. An imagewise unexposed area on the material is polymerized by imagewise exposure, heating and whole areal exposure. The photosensitive and heat-developable element comprises at least a photosensitive silver halide, an organic silver salt and a reducing agent of the formula ##STR1## The photopolymerizable element comprises at least a polymerizable polymer precursor and a photopolymerization initiator. An image forming method comprises the steps; subjecting a photosensitive material in the same layer to imagewise exposure and heating to form an image; and subjecting the resultant photosensitive material to whole areal exposure to polymerize and imagewise unexposed or exposed area thereof.
