| abstract |
A method for forming a superhigh contrast image which comprises the steps of image-exposing a silver halide photographic material having a silver halide emulsion layer provided on a support, the layer comprising silver halide grains containing 50 mol % or more of silver chloride and 1x10-8 to 1x10-6 mol of a complex of rhodium, ruthenium, rhenium, or osmium per mol of silver halide, being spectrally sensitized so as to have the maximum sensitivity in the wavelength region of 750 nm or more, and further containing a hydrazine compound; and processing with a developer which contains a developing agent of a ascorbic acid type and does not substantially contain that of a dihydroxybenzene type, the silver halide photographic material being processed with the developer which causes less harm to the environment. |
