Disclosed is a developer for silver halide photographic light-sensitive material which contains at least one of the compounds represented by the following formulas [I], [II] and [III]: Formula [I]: ##STR1## wherein M represents a hydrogen atom, an alkali metal or NH.sub.4 and A and B each represents a mercapto group, a hydroxyl group, a hydroxyalkyl group, or ##STR2## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom or --X--Y group in which X represents a divalent group and Y represents a carboxyl group or a hydroxyl group, Formula [II]: ##STR3## wherein M represents a hydrogen atom, an alkali metal or NH.sub.4, A' represents an organic divalent group, and B' represents --SO.sub.3 M', --COOM', --SO.sub.2 NHR.sub.3, --CONHR.sub.3, or --OH wherein M' represents a hydrogen atom, an alkali metal atom or NH.sub.4, and R.sub.3 represents a hydrogen atom or an alkyl group of 1-3 carbon atoms, and Formula [III]: ##STR4## wherein M and B' are the same as defined in the above formula [II]:

Developer for silver halide photographic light-sensitive material

The present invention provides a silver halide photographic photosensitive material excellent in dimensional stability which comprises a polyethylene terephthalate film support and, provided thereon, at least one gelatin layer containing an active halogen type hardener, wherein water content in the gelatin layer is 20% by weight or less based on total amount of gelatin. Further provided is a method for producing such silver halide photographic photosensitive material which comprises coating a gelatin coating solution containing an active halogen type hardener on a polyethylene terephthalate film support and then drying the coat, wherein the coat is dried so that water content based on total amount of gelatin is 20% by weight or less and then, is subjected to a heat treatment.
