There is disclosed a spectrally and chemically sensitized silver halide emulsion, which comprises silver halide grains, wherein 50% or more of total projected area of the grains is provided by tabular grains having {111} principal planes and an aspect ratio of 2.0 or more, and said tabular grains contain silver iodobromochloride or bromochloride grains each having an AgCl content of 90 mole % or more, and having angular corners. There is also disclosed a silver halide color photographic light-sensitive material containing the silver halide emulsion in at least one silver halide emulsion layer, and image-forming method comprising subjecting the material to scanning exposure, and then conducting color development. The present invention provides a silver halide emulsion, which is monodispersed, high-speed, and high contrast emulsion excellent in grain shape stability of {111} tabular grains; and, the emulsion improves high illumination reciprocity law failure and latent image stability after exposure to light. The present invention further provides a color photographic light-sensitive material using the emulsion, and image-forming method that exerts photographic characteristics of the above-described emulsion or material even when they are processed by rapid processing using a scanning exposure.
