Abstract:
1. A method of forming an image, comprising: with a toner set comprised of a plurality of toners, a first toner of the toner set comprised of toner particles comprising at least one amorphous polyester comprised of an alkoxylated bisphenol based polyester, at least one crystalline polyester derived from the reaction of an aliphatic dicarboxylic acid or aromatic dicarboxylic acid with an aliphatic diol, at least one colorant and at least one fluorescence agent, wherein the at least one colorant is a black pigment, the toner set further comprising a black toner free of fluorescence agents, wherein upon exposure to activating energy, the fluorescence agent fluoresces to cause a visible change in the color of a pattern formed in an image by the at least one toner, and wherein an image formed from the toner and under ambient light conditions exhibits a substantially same color and a substantially same gloss as that of an image formed from a same toner but not containing the at least one fluorescence agent when the image formed by the toner containing the at least one fluorescence agent and the image formed by the same toner without the at least one fluorescence agent is formed on a same substrate forming a latent image of a first pattern on a photoreceptor, developing the first pattern with the first toner, and subsequently transferring the developed first pattern to a recording medium, and forming a latent image of a second pattern on a photoreceptor, developing the second pattern with an additional toner different from the first toner, and subsequently transferring the developed second pattern to the recording medium.
