A silver halide color photosensitive material comprises blue-, green-, and red-sensitive silver halide emulsion layers on a support, and at least one layer of the material contains a compound represented by formula (I) below in an amount that satisfies a relation X/(X+Y)≧0.14, wherein X is the molar amount of the compound represented by formula (I) and Y is the molar amount of a functional coupler other than the compound represented by formula (I) in the same color-sensitive layer or the color-sensitive layers having the same color sensitivity as the color-sensitive layer to which the compound is added, or in the same non-sensitive layer to which the compound is added, Formula (I) COUP—A—E—B, wherein COUP represents a coupler moiety capable of coupling with an oxidized form of an aromatic amine-based developing agent, E represents an electrophilic portion, A represents a coupling group capable of releasing B, along with ring formation, by intramolecular nucleophilic substitution between a nitrogen atom, which originates from the aromatic amine-based developing agent and directly bonds to the coupling position in the coupling product of COUP and the oxidized form of the developing agent, and the electrophilic portion E, and B represents a development inhibitor or its precursor.
