PURPOSE: To increase sensitivity by allowing a specified compound having a group for activating silver halide grains and a latent fogging agent group before exposure and image forming.
CONSTITUTION: At least one silver halide emulsion layer contains the silver halide grains to be allowed to adsorb the compound represented by the formula; A-(Z)n-F* in which A is the group for activating the silver halide grains represented by formula I-IV; Z is a divalent bonding group; F* is a latent fogging agent group to be made an active fogging agent during a color development; and (n) us 0 or 1. In formula I-IV, Z1 is a group containing at least another hetero atom and preferably, a group necessary to complete a 5- or 6-membered ring together with the N atom; Z2 is a group necessary to complete a 5- or 6-membered ring together with the N atom; X is a -NH2 or -NH-NH2 group or the like; Y is a -S- or -NIP- group or the like; and each of B and D is an H atom or an aliphatic group or the like, thus permitting sensitivity to be further increased.
