ABSTRACT:
Disclosed is a method for producing images which comprises imagewise exposing a silver halide photographic light-sensitive material and then developing the exposed light-sensitive material in the presence of a compound represented by the following general formula [I], [II] or [III]: ##STR1## wherein Ar represents an aryl group, R represents a hydrogen atom, an alkyl group, an alkenyl group, an unsaturated hetero ring group or an aryl group and R.sub.1 and R.sub.2 each represent a hydrogen atom or a group represented by the general formula (i): ##STR2## wherein R.sub.0 represents an alkyl group, an alkenyl group, an aryl group, an alkoxy group or an aryloxy group and n is an integer of 1 or 2. ##STR3## wherein Ar, R.sub.1 and R.sub.2 are as defined in the general formula [I] and R.sub.3 and R.sub.4 each represent a hydrogen atom, an alkyl group, an aryl group, an unsaturated hetero ring group or a substituted amino group and R.sub.3 and R.sub.4 may combine with each other to form a ring, ##STR4## wherein Ar, R.sub.1 and R.sub.2 are as defined in the general formula [I] and R.sub.5 represent a nitrogen-containing hetero ring residue.
