Image forming process

In a process involving image formation followed by photographic processing which comprises contacting an image-wise exposed color photographic element comprising a support having thereon at least one silver halide emulsion containing image-wise distributed silver catalyst nuclei with an intensifier containing at least one intensifying agent selected from the group consisting of peroxides, halogenous acids and cobalt (III) complex compounds, in the presence of a reducing agent, which is in a processing solution or the element, and thereby image-wise oxidizing the reducing agent and conducting image intensification by the oxidized reducing agent, the improvement comprising that (1) at least one compound represented by the following general formula having a polymerization degree of 1 -- 8,000;

• --(A).sub.x -- (B).sub.y --
• wherein A represents ##STR42## or --CH.sub.2 --CH.sub.2 --O--, wherein R represents ##STR43## or --OH, with m being an integer of 3 - 7, R.sub.1 is an alkyl group having 1 to 6 carbon atoms, and R.sub.2 is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms,
• B represents a monomer unit derived from styrene, methacrylic acid ester, acrylic acid ester, vinyl acetate, acrylonitrile, vinyl alcohol, vinyl chloride, vinyl ether, acrylamide, N,N-dimethylacrylamide, acrylic acid, methacrylic acid, maleic acid, potassium styrenesulfonate, N,N-dialkylaminoalkyl methacrylate, vinyl imidazole or vinyl pyridine, and (2) an antifoggant being at least one nitrogen containing hetero ring compound having no mercapto group are both contained in said intensifier or a developing bath prior to said intensifier.
