Summary:PROBLEM TO BE SOLVED: To obtain a silver halide photographic sensitive material enabling slight replenishment and slight discharge of a developing soln., etc., having satisfactory color forming property and preservability, giving an image having high sharpness and less liable to color mixing by incorporating a specified color developing agent and a polymer coupler which is a specified homo- or copolymer. SOLUTION: This silver halide photographic sensitive material contains a color developing agent represented by formula I and a polymer coupler which is a homopolymer derived from a coupler monomer represented by formula II or a copolymer of the coupler monomer with a monomer forming no color and having an ethylene group incapable of coupling with the oxidized body of the color developing agent in one of the photographic constituent layers. In the formulae I, II, R is aryl or a heterocyclic group, R is alkyl, alkenyl, etc., X is -SO2 -, -CO-, etc., R is H, Cl, etc., L is -C (=O) O-, etc., L is a divalent combining group, each of (i) and (j) is 0 or 1 and Q is a residue of a coupler capable of forming a dye by coupling with the oxidized body of the developing agent represented by the formula I.
