Silver halide photosensitive material and image-forming method using same

摘要

The second silver halide photosensitive material comprises a substrate and at least one photosensitive silver halide emulsion layer formed thereon, the silver halide photosensitive material comprising at least two types of silver halide grains with different projected areas having photosensitivity in the same spectral range; silver halide grains having a larger projected area having a refractive index n1 and an average thickness a, and silver halide grains having a smaller projected area having a refractive index n2 and an average thickness b; and the silver halide grains satisfying the conditions defined by the following equation (1): <?in-line-formulae description="In-line Formulae" end="lead"?>n2<=N1, ANDa<=Bx(n2/n1) (1). <?in-line-formulae description="In-line Formulae" end="tail"?>
