ABSTRACT:
A method of developing silver halide photographic material which contains a light-sensitive silver halide emulsion and an internally-fogged silver halide emulsion, in which the internally-fogged emulsion has internal fogging nuclei at a depth of 0.02.mu. or more below the surface of the grains is disclosed. The photographic material is developed in the presence of at least one compound selected from the group consisting of tetraazaindenes containing at least one mercapto group, purines containing at least one mercapto group, triazaindenes containing at least one mercapto group and pentaazaindenes containing at least one mercapto group, to increase photographic speed, contrast and maximum density as well as remove uneven stain.
