ABSTRACT:
A silver halide photographic material having a high covering power with improved pressure resistance and antistatic properties upon development, which comprises at least one silver halide photographic emulsion layer disposed on at least one side of a support, wherein at least one of the silver halide photographic emulsion layer(s) contains a photosensitive silver halide emulsion containing silver iodide and an internally fogged silver halide emulsion, and at least one of the silver halide photographic emulsion layer(s) and an auxiliary layer(s) which is disposed on the same side of the support as that of the support having said emulsion containing silver iodide contains at least one polyoxyethylenic surface active agent selected from the group consisting of compounds represented by formula (I) and (II) ##STR1## wherein R.sub.1, R.sub.2, R.sub.6, R.sub.8, R.sub.10, and R.sub.12 each represents a hydrogen atom, a substituted or unsubstituted alkyl group, aryl group alkoxy group, or aryloxy group, a halogen atom, an acyl group, an amido group, a sulfonamido group, a carbamoyl group, or a sulfamoyl group, R.sub.5, R.sub.7, R.sub.9 and R.sub.11 each represents a substituted or unsubstituted alkyl group, aryl group alkoxy group, or aryloxy group, a halogen atom, an acyl group, an amido group, a sulfonamido group, a carbamoyl group, or a sulfamoyl group; R.sub.3 and R.sub.4 each represents a hydrogen atom, a substituted or unsubstituted alkyl group, aryl group, or heterocyclic aromatic ring, or groups in at least one combination of R.sub.3 and R.sub.4, R.sub.5 and R.sub.6, R.sub.7 and R.sub.8, R.sub.9 and R.sub.10, and R.sub.11 and R.sub.12 are connected to each other to form a substituted or unsubstituted ring; n.sub.1, n.sub.2, and n.sub.3 each represents the average polymerization degree of ethylene oxide within the range of from 5 to 50; and m represents an average polymerization degree of from 5 to 50.
