Abstract:
To provide a toner, containing: a binder resin; a crystalline polyester resin; a colorant; and wax, wherein the toner has a fluidized powder characteristic value of 35% to 45%, and a BET specific surface area of 2.8 m2/g to 4 m2/g, and wherein the toner has an intensity ratio P2850/P828 of 0.10 to 0.20, where P2850 is an intensity of a peak at 2850 cm−1 which is attributed from the wax and the crystalline polyester resin, and P828 is an intensity of a peak at 828 cm−1 which is attributed from the binder resin, as measured by total reflectance infrared spectroscopy.
