Claims16
A method for forming an image, comprising developing a silver halide photographic light-sensitive material in the presence of a compound represented by general formula (A):
- general formula (A) ##STR33## wherein R.sub.1 and R.sub.2 each represent an alkyl group, an aryl group, or a heterocyclic group;
- X represents a hydrogen atom, an acyl group, or a sulfonyl group;
- Z represents two or more non-metal atoms necessary to complete a 5- or 6-membered heterocyclic nucleus;
- and R.sub.3 represents an alkyl group, an aryl group, a heterocyclic group, --OR.sub.4, or --NR.sub.5 R.sub.6, wherein R.sub.4, R.sub.5, and R.sub.6 each represent an alkyl group, an aryl group, or a heterocyclic group, with the proviso that R.sub.6 may be a hydrogen atom.
