    Abstract: Treated metal oxide particles include metal oxide particles treated with at least a charge modifying agent. The charge modifying agent is represented by the following formula: An-Z c -Y b -Ar(EW) a, wherein Ar represents an aromatic group, EW represents an electron withdrawing group, Y represents a spacer group, Z represents an alkylene group, An represents an anchor group, a is an integer from 1 to 5, b is 0 or 1, and c is 0 or 1. The treated metal oxide particles may also be treated with a second charge modifying agent or with a hydrophobicity-imparting agent. A toner composition including toner particles and treated metal oxide particles is also disclosed.

    Abstract: The invention provides hydrophobic surface-treated silica particles having (1) a ratio T2:T3 of about 0.4 or more, wherein T2 is the intensity of a peak having a chemical shift in the CP/MAS 29 Si NMR spectrum centered within the range of -56 ppm to -59 ppm, and wherein T3 is the intensity of a peak having a chemical shift in the CP/MAS 29 Si NMR spectrum centered within the range of -65 ppm to -69 ppm, and (2) a ratio (T2 +T3) / (T2 +T3 +M) of greater than about 0.05, wherein M is the intensity of a peak having a chemical shift in the CP/MAS 29 Si NMR spectrum centered within the range of +7 ppm to +18 ppm. The invention also provides a method of preparing hydrophobic surface-treated silica particles.

    Abstract: 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.
