This invention provides a silver halide emulsion, a silver halide photographic material and an image forming method, which is excellent in high sensitivity, good gradation, coating composition store stability and latent image store stability regardless exposing method, particularly excellent latent image store stability at high intensity and shot period exposure of digital exposure, and by which a high quality print is obtained. The silver halide emulsion contains silver halide grains having silver chloride content of at least 90 mol %, silver iodide content of 0-2.0 mol %, and silver bromide content of 0.02-5.0 mol %, and containing at least two kinds of Group 8 metal compounds containing at least one iridium compound inside of the silver halide grains, in which the silver halide grains are subjected to selenium sensitization in presence of a compound represented by formula (S)
A silver halide emulsion containing silver halide grains having silver chloride content of at least 90 mol %, silver iodide content of 0-2.0 mol %, and silver bromide content of 0.02-5.0 mol %, and containing at least two Group 8 metal compounds, including at least one iridium compound, inside of the silver halide grains, wherein the silver halide grains are subjected to selenium sensitization in presence of a compound represented by formula (S)
The silver halide emulsion containing silver halide grains having silver chloride content of at least 90 mol %, silver iodide content of 0-2.0 mol %, and silver bromide content of 0.02-5.0 mol %, and containing at least two Group 8 metal compounds, including at least one iridium compound, inside of the silver halide grains, wherein the silver halide grains contains at least one compound represented by formula (1) to (3), and the silver halide grains are subjected to selenium sensitization,
The silver halide emulsion containing silver halide grains having silver chloride content of at least 90 mol %, silver iodide content of 0-2.0 mol %, and silver bromide content of 0.02-5.0 mol %, and containing at least two Group 8 metal compounds, including at least one iridium compound, inside of the silver halide grains, wherein the silver halide grains contain a compound represented by formula (4), and the silver halide grains are subjected to selenium sensitization,
The silver halide emulsion containing silver halide grains having silver chloride content of at least 90 mol %, silver iodide content of 0-2.0 mol %, and silver bromide content of 0.02-5.0 mol %, and containing at least two Group 8 metal compounds, including at least one iridium compound, inside of the silver halide grains, wherein the silver halide grains contain a crown ether compound condensed by at least one aromatic ring, and the silver halide grains are subjected to selenium sensitization.
