<P>PROBLEM TO BE SOLVED: To provide toner additives that serve as spacers between toner particles, where the toner particles exhibit limited embedding in the toner particles and limited drop-off without adverse impact on triboelectric charging characteristics of the toner. <P>SOLUTION: A toner composition comprises toner particles and toner additives. The toner additives comprise metal oxide-polymer composite particles comprising a metal oxide and a polymer. The metal oxide-polymer composite particles are distributed on surfaces of the toner particles. The metal oxide particles are covalently attached to the polymer, and surfaces of the metal oxide are modified with a first hydrophobizing agent. <P>COPYRIGHT: (C)2013,JPO&INPIT |
