Abstract (en)
Disclosed is a developer composition for a silver halide photographic light-sensitive material, which comprises a dihydroxybenzene type developing agent, at least one of a auxiliary developing agent selected from 1-phenyl-3-pyrazolidone and p-aminophenol, a sulfite, wherein the amount of said sulfite is not less than 0.3 mol per liter of a developing solution, and an amine compound represented by Formula I; <CHEM> wherein R1 is an alkyl group or a carbonyl group, R2 is an alkyl group, R3, R4, R5 and R6 each represent an alkyl group, and n is an integer of 1 to 5. A developer solution containing the developer composition is capable of providing a ultra high-contrast photographic characteristics without failing a sensitivity of a silver halide photographic light-sensitive material.
