Abstract
The present invention provides an image forming method for obtaining excellent color fixed images with a smaller amount of light energy. This image forming method includes the steps of: forming a toner layer of a color toner containing at least a binder resin, a coloring agent, and an infrared absorbent, on a recording medium; and fixing the toner layer by flashlight emission, where the relationship among the PAS level S of the color toner that is obtained by integrating an infrared PAS spectrum obtained through PAS (photoacoustic spectroscopy) analysis in the range of 800 nm to 2000 nm, the melt viscosity ρ of the color toner at a reference temperature, and the energy E of the flashlight, is expressed by the following relational expression:1000≦ρ/≦5500.
