To attain a producing method of a color filter without producing a rough surface state of an image or without bleeding in a matrix pattern.

A silver halide photosensitive material produced by applying a photographic structure layer containing at least a photosensitive silver halide emulsion on a supporting body is exposed according to a pattern, and developed in the presence of a color developing agent and at least one kind of coupler to produce a color filter having pixel patterns of blue, green and red colors.
