PROBLEM TO BE SOLVED: To provide a photosensitive silver halide emulsion exhibiting a low fog and high sensitivity, a silver halide photosensitive material, and a heat developable photosensitive material excellent in image preservability before and after development. SOLUTION: The silver halide emulsion comprises gelatin and silver halide grains having an average AgI content of≥40 mol%,≥50% of a total projected area of the silver halide grains being occupied by silver halide grains having an aspect ratio of≥2, wherein the gelatin is an amino group-modified gelatin in which≥20% of all amino groups have been modified.
