摘要

A color toner for electrophotography, preferably used as a flash fixing toner which can be processed at a high speed, and exhibit excellent fixing property, high image resolution (image reproducibility) when fixed, and color reproducibility by color overlapping, and having a preferable color tone, with which a multi-color image can be formed. The color toner for electrophotography is used for the extreme bottom layer of a multi-color image comprised of laminating at least two types of toners that are selected from black toner, magenta toner, yellow toner, and cyan toner, and contains a coloring agent and an infrared ray absorbent, the color toner for electrophotography has a contrast ratio in the range of 35% to 95%.
