Abstract
Abstract There is disclosed a processing method of a light-sensitive silver halide photographic material to be used in a method for forming an image be developing and fixing a negative type light-sensitive silver halide photographic material having at least one layer of light-sensitive silver halide emulsion layer on a support, which comprises the silver density on the emulsion layer side of said light-sensitive silver halide photographic material is 0.5 g/cm 2 or higher and also a hydrazine derivative is contained in said layer, and the light-sensitive silver halide photographic material is processed within a developing time of 15 seconds.
