| 简介 |
An electrophotographic toner showing good cleanability and is suitable for use in developing an electrostatic latent image formed on an amorphous-silicon photosensitive member is provided. The toner includes toner particles each comprising a binder resin and a colorant, and inorganic fine powder A. The inorganic fine powder A contains 88.0 - 97.0 wt. % of a rare earth compound comprising a rare earth oxide. The rare earth compound contains 40.0 - 65.0 wt. % of Ce (calculated as CeO2), 25.0 - 45.0 wt. % of La (calculated as La2O3), 1.0 - 10.0 wt. % of Nd (calculated as Nd2O3) and 1.0 - 10.0 wt. % of Pr (calculated as Pr6O11). The rare earth compound contains further a fluorinated rare earth compound in such an amount as to provide the inorganic fine powder A with a fluorine content of 2.0 - 11.0 wt. %. |
