摘要： A silver halide photographic light-sensitive material has at least one silver halide emulsion layer on a support, wherein the silver halide emulsion layer contains a silver halide emulsion consisting of tabular silver halide grains not containing a cavity extending through two major planes opposing each other and having an average aspect ratio of 1.5 or more, except that 20% or more of the tabular silver halide grains started to be developed containing a cavity extending through the major planes when the silver halide emulsion was developed with a color developer containing a silver halide solvent and a p-phenylenediamine-based color developing agent for 60 sec. A method for forming images includes the step of performing color development for the material for 25 to 90 sec by using a color developing solution containing thiosulfate, methanethiosulfonate, thiocyanate or at least one of the silver halide solvents represented by the formula (A), (B), (C), (D) and (E) each defined in the specification.
