The present invention provides a color toner kit that uses yellow toner, cyan toner, magenta toner, and black toner to ensure the color tone (color reproduction range) of process ink. In a color toner kit used for a full-color image forming method having yellow toner, cyan toner, and magenta toner, In the spectral distribution diagram with the vertical axis representing the reflectance (%) and the horizontal axis representing the wavelength (nm), the reflectance determined as the toner in the powder state is in the range of 15 to 20% at the wavelength of 500 nm, and A yellow toner having a wavelength of 600 nm and a range of 75 to 80%; Cyan toner having a reflectance similar to the above in the range of 30 to 35% at a wavelength of 450 nm and 35 to 40% at a wavelength of 475 nm; The magenta toner having the same reflectance as described above is in the range of 5 to 10% at a wavelength of 425 nm and 65 to 70% at a wavelength of 675 nm.
