Abstract:
Provided is a cyan toner which, while being a capsule-type toner having excellent low-temperature fixability, has excellent offset resistance and charging performance and can obtain high-quality images. A cyan toner having at least a resin (a) having a polyester as a main component, a colorant, and a wax, in which glass transition temperatures (° C.) Tg(0.5) and Tg(4.0) obtained at a rate of temperature increase of 0.5° C./min or 4.0° C./min satisfy 40.0≦Tg(0.5)≦60.0 and 2.0≦Tg(4.0)−Tg(0.5)≦10.0, and wherein, when the concentration of the cyan toner in an ethyl acetate dispersion is Cc1 (mg/ml), and the light absorbance at a wavelength of 712 nm of the dispersion is A(ethyl acetate)712, A(ethyl acetate)712/Cc1
