A negative-tupe silver halide photographic material is provided, having high sensitivity and good graininess with low fog. The material has at least one silver halide emulsion layer on a support, wherein chemically-sensitized silver halide grains contained in the emulsion of said emulsion layer comprise normal crystalline grains, and said emulsion layer containing said normal crystalline silver halide grains contains a polymer having a repeating unit represented by formula (I): <IMAGE> (I) wherein R1 represents a hydrogen atom or an alkyl group; Q represents one group selected from formulae (i), (ii), (iii), and (iv); <IMAGE> (i) wherein q is an integer of from 2 to 4; <IMAGE> (ii) wherein R2 and R3 each represents a hydrogen atom or an alkyl group; <IMAGE> (iii) wherein Z1 represents an atomic group forming a lactam ring, an oxazolidone ring, or a pyridone ring; A represents a single bond, <IMAGE> B represents -O- or <IMAGE> wherein R4 represents a hydrogen atom or an alkyl group; and l is an integer of from 1 to 6; and <IMAGE> (iv) wherein a has the same meaning as defined for formula (iii); D represents a single bond, -O- or <IMAGE> wherein R5 represents a hydrogen atom, an alkyl group, or <IMAGE> wherein R6 represents an alkyl group; and m and n each represents an integer of from 1 to 6, provided that the sum of m and n is an integer of from 4 to 7.
