摘要:
A black toner has a toner particle including at least a resin (a) having a polyester as a main component, carbon black, and a wax, and a fine inorganic particle. When the Tgs of the black toner measured by DSC at temperature rise rate of 0.5° C./min and 4.0° C./min are defined as Tg(0.5) and Tg(4.0) respectively, Tg(0.5) is 35.0 to 60.0° C. and the difference between Tg(4.0) and Tg(0.5) is 2.0 to 10.0° C. When preparing a solution of which the black toner is dissolved in ethyl acetate and defined the concentration thereof as Cb1 (mg/mL) and the light absorbance thereof at 600 nm wavelength as A600, A600/Cb1 is less than 0.15. When preparing a solution of which the black toner is dissolved in chloroform and defined the concentration thereof as Cb2 (mg/mL) and the light absorbance thereof at 600 nm wavelength as A600, A600/Cb2 is 2.00 to 6.55.
