Patent ID: 6905808

Claim:
A full-color image-forming method comprising the steps of: passing a recording material having thereon at least a yellow toner image, a cyan toner image and a magenta toner image through a heat-and-pressure fixing means; heat-and-pressure fixing the yellow toner image, the cyan toner image and the magenta toner image onto the recording material; and forming a full-color image on the recording material, wherein the yellow toner image is formed using a yellow toner in which, in a spectral-distribution diagram in which reflectance (%) is plotted as ordinate and 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; wherein the cyan toner image is formed using a cyan toner in which, in a spectral-distribution diagram in which reflectance (%) is plotted as ordinate and wavelength (nm) as abscissa, 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 wherein the magenta toner image is formed using a magenta toner in which, in a spectral-distribution diagram in which reflectance (%) is plotted as ordinate and wavelength (nm) as abscissa, 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.
