<p>PROBLEM TO BE SOLVED: To reduce used light energy and to provide color toner for flash fixing with which an excellent image is formed. SOLUTION: This color toner incorporates at least a binding resin, a colorant and an infrared ray absorbent, and is fixed on a recording medium by flash light, and PAS intensity obtained by integrating infrared ray PAS spectrum obtained based on optoacoustic spectroscopic (PAS) analyzing measurement with in 800 to 2,000 nm is set within 0.01-0.2 when carbon black is '1'.</p> |
