Abstract
A yellow toner is provided which can form high-quality images and has high offset resistance and excellent charging performance while being a capsule-type toner having excellent low-temperature fixability. The yellow toner satisfies, in DSC measurement, 40.0≦Tg(0.5)≦60.0 and 2.0≦Tg(4.0)−Tg(0.5)≦10.0, wherein when the concentration of the yellow toner in an ethyl acetate dispersion is C(mg/ml) and the light absorbance at a wavelength of 422 nm of the dispersion is A(ethyl acetate), the relationship between Cand A(ethyl acetate)satisfies A(ethyl acetate)/C<0.45, and when the concentration of the yellow toner in a chloroform solution is C(mg/ml) and the light absorbance at a wavelength of 422 nm of the solution is A(chloroform), the relationship between Cand A(chloroform)satisfies 6.00<A(chloroform)/C<14.4.
