Patent ID: 8841051

Claim:
A method for forming a full color image using at least a yellow toner, a magenta toner, a cyan toner (1) and a cyan toner (2), the method comprising the steps of: (a) forming a toner image by developing an electrostatic latent image formed on an electrostatic latent image carrier by employing a developer, (b) transferring the toner image formed on the electrostatic latent image carrier onto an image support, and (c) fixing the toner image transferred onto the image support, wherein a toner image formed by using solely the cyan toner (1) exhibits: a maximum chroma C* of 50 or more; and a lightness L* of 30 to 52 in a color space represented by L*a*b* colorimetric system, a toner image formed by using solely the cyan toner (2) exhibits: a maximum chroma C* of 50 or more; and a lightness L* of 58 to 75 in a color space represented by L*a*b* colorimetric system; and the cyan toner (2) contains a colorant represented by Formula (I): wherein M 1 represents a silicon atom, and Z 1 represents Formula (II): wherein Z 2 to Z 4 each independently represents an alkyl group of 1 to 22 carbon atoms; and aryloxy group of 6 to 18 carbon atoms; or an alkoxy group of 1 to 22 carbon atoms, and A 1 to A 4 each independently represents a group of atoms which forms a benzene ring.
