A photographic developing agent represented by the formula (I): <IMAGE> (I) wherein one of X and Y is a group capable of inhibiting development on release immediately after the developing agent is oxidized at the step of development, and the other of X and Y is an -NH-SO2-Z group (wherein Z is an alkyl group, an aryl group or a heterocyclic group); A is a hydrogen atom or a group hydrolyzable under alkaline conditions; R1, R2, and R3, which may be the same or different, each is a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, an alkoxy group, an aryloxy group, an -S-Z' group (wherein Z' is an alkyl group, an aryl group or a heterocyclic group), an -NH-SO2-Z'' group (wherein Z'' is an alkyl group, an aryl group or a heterocyclic group), an acylamido group, an amino group, a halogen atom, a hydroxy group, or an acyloxy group; and R1 and R2 further may combine to form a ring, a silver halide photographic light-sensitive material having a photographic layer containing at least one compound selected from the compounds represented by the above formula (I), and a process for developing images by treating a photographic light-sensitive material with a developer containing at least one compound selected from the compounds represented by the above formula (I).
