Abstract
A processing method for silver halide photogrphic
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 tri-
hydroxybenzene type compound; a sulfite and an amino compound
in the presence of a compound represented by the following
Formula 1, 2 and 3;
