The present invention provides a process for development of a black-and-white silver halide photographic material, which comprises use of a development replenisher for black-and-white silver halide photographic material comprising an ascorbic acid and/or derivative thereof which has a pH value of at least 0.5 higher than that of the development starting solution.
