ABSTRACT:
A toner is provided including a binder resin and a wax having primarily C—H and C—C bonds, and having a melting point of 50 to 90° C., wherein the wax is present in a surface portion of the toner in an amount of from 0.1 to 4.0% by weight, wherein the amount of the wax is determined by Fourier transform infrared spectroscopy attenuated total reflectance (FTIR-ATR); and the use of the toner in an image forming method, image forming apparatus, developer and toner cartridge containing the toner.
