A silver halide photographic material capable of providing very high contrast image and having improved safelight safety is described, which comprises a support having thereon at least one silver halide emulsion layer, and containing in the silver halide emulsion layer or another hydrophilic colloid layer (i) a compound represented by formula (I) ##STR1## wherein PWR represents a group capable of releasing ##STR2## upon being reduced; Time represents a group capable of releasing LA after being released from PWR, t is 0 or 1; and LA represents a group having an absorption maximum in the wavelength region longer than 310 nm, (ii) a hydrazine derivative, and (iii) at least one compound represented by formulae (IX) and (X) ##STR3## wherein R.sup.91, R.sup.92, R.sup.93, and R.sup.94, which may be the same or different, each represents hydrogen, an alkyl group, an aryl group, an amino group, a hydroxyl group, an alkoxy group, an alkylthio group, a carbamoyl group, a halogen atom, a cyano group, a carboxyl group, an alkoxycarbonyl group or a heterocyclic group and R.sup.91 and R.sup.92 or R.sup.92 and R.sup.93 may be linked to form a 5- or 6-membered ring; provided that at least one of R.sup.91 and R.sup.93 represents a hydroxyl group.
