ABSTRACT:
A method for forming an image comprising the steps of: (a) imagewise exposing silver halide photographic materials; where said photographic material contains (1) a compound represented by formula (I) ##STR1## wherein R.sub.1 represents an aliphatic group or an aromatic group; R.sub.2 represents a hydrogen atom, an alkyl group, or an aryl group, an alkoxy group, an aryloxy group, an amino group, a carbamoyl group, or an oxycarbonyl group; G.sub.1 represents a carbonyl group, a sulfonyl group, a sulfoxy group, ##STR2## or an iminomethylene group; and A.sub.1 and A.sub.2 both represent a hydrogen atom, or one of A.sub.1 or A.sub.2 represents a hydrogen atom and the other represents a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, or a substituted or unsubstituted acyl group, and (2) a redox compound that can release a development inhibitor when oxidized; and (b) subjecting said imagewise exposed silver halide photographic materials to development-processing where a bath used in said development-processing contains a nucleation development accelerator.
