PROBLEM TO BE SOLVED: To provide a color toner kit capable of ensuring the color tones (color reproduction ranges) of process inks with a yellow toner, a cyan toner, a magenta toner and a black toner. SOLUTION: In the color toner kit for use in a full-color image forming method having a yellow toner, a cyan toner and a magenta toner, the toners are a yellow toner in which, in a spectral-distribution diagram in which the reflectance (%) is plotted as ordinate and the wavelength (nm) as abscissa, the reflectance determined for a toner in a state of powder ranges from 15% to 20% at a wavelength of 500 nm and ranges from 75% to 80% at a wavelength of 600 nm, a cyan toner in which, in the like spectral-distribution diagram, the reflectance determined for a toner in a state of powder ranges from 30% to 35% at a wavelength of 450 nm and ranges from 35% to 40% at a wavelength of 475 nm, and a magenta toner in which, in the like spectral-distribution diagram, the reflectance determined for a toner in a state of powder ranges from 5% to 10% at a wavelength of 425 nm and ranges from 65% to 70% at a wavelength of 675 nm.
