Abstract (en)
[origin: EP0908764A1] A method of processing an exposed black-and-white silver halide light-sensitive photographic material has been disclosed, said method comprising the steps of developing in a developer solution, followed by fixing in a fixer solution, comprising a hardening agent, preferably a compound providing aluminum ions, and wherein, in running equilibrium conditions, said fixer solution has a pH of at least 4.3, further adding to said fixer a fixer replenisher at a rate of from 0 ml/m<2> up to 300 ml/m<2>; followed by rinsing and drying, wherein rinsing between developing and fixing is excluded and wherein an alpha -ketocarboxylic acid structure in an amount of from 0 to 3 g per litre is present in the said fixer solution while starting processing or in the said fixer replenisher, characterized in that said developing step is performed in a developer comprising, in an amount of from 5 g up to 100 gram per litre, a developing agent correspon-ding to the formula (I), a precursor and/or a metal salt thereof given in the detailed description and in the claims hereinafter. Most preferably l-ascorbic acid, iso-ascorbic acid or (tetramethyl) reductic acid is used as a developing agent.
