Method of forming color images

A method of forming a color image, comprising forming an original image on an image-forming material and duplicating the formed original image on a color photosensitive material for use in the duplication, the color photosensitive material for use in the duplication comprising at least one blue-sensitive silver halide emulsion layer containing a yellow coupler, at least one green-sensitive silver halide emulsion layer containing a magenta coupler and at least one red-sensitive silver halide emulsion layer containing a cyan coupler on a support of a transmission-type or reflection-type,

• wherein the formed original image contains a dye formed from a cyan coupler represented by the following general formula (CC-1):
• 65
• wherein Ga represents —C(R13)═ or —N═;
• Gb represents —C(R13)═ when Ga represents —N═, or Gb represents —N═ when Ga represents —C(R13)═;
• each of R11 and R12 represents an electron-withdrawing group having a Hammett substituent constant σp value of 0.20 to 1.0;
• R13 represents a substituent;
• and Y represents a hydrogen atom or a group capable of splitting-off by a coupling reaction with an oxidized product of an aromatic primary amine color developing agent;
• and
• wherein with respect to the red-sensitive silver halide emulsion layer of the color photosensitive material for use in the duplication, the maximum sensitivity wavelength, λmax (D), of spectral sensitivity distribution at each density satisfies the relationship:
• 630 nm≦λmax (D)≦670 nm.
