ABSTRACT:
Disclosed is a method for developing a silver halide photographic material, which comprises processing the silver halide photographic material having at least one silver halide emulsion layer containing silver halide grains, with a substantially hydroquinone-free developing solution containing (i) a compound represented by formula (A) as a developing agent, wherein at least 50% of the sum of the projected area of the silver halide grains are tabular silver halide grains having an aspect ratio of 3.0 or more, and said developing solution contains (ii) a compound represented by formula (B): ##STR1## wherein R.sub.1 represents a hydrogen atom, an alkyl group, an aryl group or a heterocyclic group; and ##STR2## wherein X represents an oxygen atom or a sulfur atom, Y represents a hydrogen atom or a substituent group, and M represents a hydrogen atom, an alkali metal ion, a quaternary ammonium ion or a quaternary phosphonium ion.
