ABSTRACT:
A photographic silver halide photosensitive material comprising a silver halide emulsion of silver halide grains containing at least 20 mol % of AgCl, tabular grains having an aspect ratio of at least 2 accounting for at least 50% of the projected area of all silver halide grains, and having a Ag coverage of 0.5-1.5 g/m.sup.2 and a gelatin coverage of 0.7-2.1 g/m.sup.2 per one surface and a swelling factor of less than 180% is processed through an automatic processor by replenishing a developer containing an ascorbic acid type compound as a developing agent in an amount of 25-150 ml/m.sup.2 and a fixer in an amount of 13-300 ml/m.sup.2. The invention is successful in producing images of quality while reducing the amounts of replenishment and spent solutions, increasing processing stability, and eliminating silver sludging.
