Method for the formation of high-contrast images using a developer comprising a hydrazine derivative |
摘要 |
A processing method for silver halide photographic material is disclosed, which stably provides images having high contrast and high dot quality with little degradation in sensitivity by rapid processing. In the method, a silver halide light-sensitive material having a silver halide emulsion layer containing a 3-pyrazolidone type compound, a dihydroxybenzene type compound or trihydroxybenzene type compound, is developed by a developer containing a di- or trihydroxybenzene type compound; a sulfite and an amino compound in the presence of a compound represented by the following Formula 1, 2 and 3; <IMAGE> Formula 1 <IMAGE> Formula 2 <IMAGE> Formula 3
