More Information
Summary:A toner includes a toner particle containing a binder resin and an inorganic infrared absorbent particle, wherein (1) in spectrometry of a fixed image obtained by fixing an unfixed image formed on a recording material by using the toner in a loading amount of 0.30 mg/cm2, a maximum value of a light absorbance in a wavelength range of 400 nm or more and 800 nm or less is 10% or less, and (2) in cross section observation of the toner particle using a transmission electron microscope, when a circle having the center of gravity of a cross section image of the toner particle as the center thereof and having a radius of 2.0 μm is drawn and the circle is divided into four to form four quadrants, a coefficient of variation in number of the inorganic infrared absorbent particles observed in each quadrant is 0.50 or less.
