A magenta toner characterized by satisfying, in DSC measurement, 40.0≦Tg(0.5)≦60.0 and 2.0≦Tg(4.0)-Tg(0.5)≦10.0, wherein when preparing a solution of which the magenta toner is dissolved in ethyl acetate, and defined the concentration of the thereof as Cm1 (mg/ml), and the light absorbance thereof at a wavelength of 538 nm as A(ethyl acetate)538, the ratio of A(ethyl acetate)538 to Cm1 satisfies the formula, A(ethyl acetate)538/Cm1<0.15, and, when preparing a solution of which the magenta toner is dissolved in chloroform, and defined the concentration of the thereof as Cm2 (mg/ml), and the light absorbance thereof at a wavelength of 538 nm as A(chloroform)538, the ratio of A(chloroform)538 to Cm2 satisfies the formula, 2.00<A(chloroform)538/Cm2<6.55.
