Surface-treated metal oxide particles |
摘要 |
The invention provides surface-treated metal oxide particles. The surface-treated metal oxide particles have specific ratios of (1) the integrated area of the resonance signals with chemical shifts in the range from −4 ppm to −33 ppm to the integrated area of the resonance signals with chemical shifts in the range from −33 ppm to −76 ppm and (2) the integrated area of the resonance signals with chemical shifts in the range from −76 ppm to −130 ppm to the integrated area of the resonance signals with chemical shifts in the range from −33 ppm to −76 ppm in the CP/MAS 29Si NMR spectrum. The invention further provides a toner composition for electrophotographic image formation comprising toner particles and surface-treated metal oxide particles.
