A silver halide photographic material containing at least one of compounds represented by formula (I) and salts thereof in at least one hydrophilic colloidal layer of the silver halide photographic material gives photographic images having stable and excellent quality without being accompanied by the increased formation of fog and increased changes of sensitivity and gradation upon high temperature processing: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic ring group; or one or both of said R.sub.1 and R.sub.2 and said R.sub.3 and R.sub.4 combine with each other to form a ring.
