Zusammenfassung: | A toner external additive composition of the present invention comprises, as a core component, tin oxide, to be usable as an alternative material for conventional titanium dioxide (TiO2), and thus can respond to future regulations on titanium dioxide and environment. In addition, the toner external additive composition and a toner composition comprising same comprise, as a shell component, a silane-based compound and aluminum hydroxide to reduce triboelectric charge so that a ghost phenomenon is alleviated and increase image density so that print quality is improved. Particularly, if aluminum hydroxide is used in a specific amount range, a print quality improvement effect can be further improved. |
