Image-forming method

An image-forming method, comprising the steps of:

• providing a silver halide color photographic material;
• imagewise exposing the material;
• and
• color-developing the exposed material in the presence of a nitrogen-containing heterocyclic compound having the general formula (I) or (II):
• ##STR6## wherein A is an alkyl group, an alkenyl group, an alkynyl group, an aralkyl group, an alicyclic hydrocarbon group, or an aryl group, each of which may be substituted, B is a substituted or unsubstituted di-valent hydrocarbon group, X is an anion other than iodide and Z is a non-metallic group which forms a heterocyclic ring with a nitrogen atom, wherein said compound is capable of reacting with or being adsorbed into a silver halide, with a mono-bath intensifying developing solution which includes hydrogen peroxide or a compound capable of releasing hydrogen peroxide and a color developing agent, the solution substantially excluding the presence of bromide ions and iodide ions.
