PURPOSE: To form a magenta image good in color reproducibility by developing a silver halide photosensitive material in the presence of a specified coupler and/ or a polymer or copolymer coupler derived from a vinyl monomer having this specified part in the molecule with a developing soln. contg. aromatic primary amine. CONSTITUTION: A silver halide photosensitive material is developed with a developing soln. contg. aromatic primary amine in the presence of a coupler of the formula (R 1 , R 2 are each H or a substitute, and X is H or a group releasable by coupling reaction), or a polymer or copolymer coupler derived from a vinyl monomer having said part of the formula in the molecule. As a result, the subabsorption of 5-pyrazolone type coupler near 430nm can be eliminated, and color reproducibility, color developing speed, and max. color density can be improved. The coupler can be converted into a so-called 2-equiv. type by introducing a releasable group to the active site of coupling, and therefore, a magenta image capable of cutting down an amt. of silver to be used can be formed.
