Abstract

A silver halide photosensitive material containing a compound selected from Types 1-4 below which is capable of undergoing a one-electron oxidation to form a one-electron oxidation product (OEOP), and a reducing compound (Type 1) the OEOP is capable of releasing further two or more electrons accompanying a subsequent bond cleavage reaction, (Type 2) the OEOP is capable of releasing further one electron accompanying a subsequent bond cleavage reaction, and the compound having, in its molecule, two or more groups adsorptive to silver halide, (Type 3) the OEOP is capable of releasing further one or more electrons after going through a subsequent bond forming process, and (Type 4) the OEOP is capable of releasing further one or more electrons after going through a subsequent intramolecular ring cleavage reaction.
