An internal latent image-type direct positive silver halide photographic emulsion is disclosed, comprising a silver halide grain prepared to have a composite structure such that the iodide content of the silver halide in the silver halide phase formed on the surface of a silver halide grain is higher than the iodide content of the silver halide in the phase on the inner side, wherein the average iodide content of all grains is less than 1.0 mol % and the amount of iodide supplied for the silver halide phase formed on the surface of the grain is from 0.005 mol % to less than 0.3 mol % based on all grains. Also disclosed is a color diffusion transfer light-sensitive material using the emulsion.
