Abstract
The disclosure relates generally to toner additives, and in particular, toner additives that provide desired higher toner charge and low relative humidity (RH) sensitivity. The toner additives comprise titania nanotubes or titania nanosheets in combination with or in place of the commonly used anatase or rutile crystalline titania.
Claims21
A toner composition comprising:
- toner particles comprising a resin and a colorant;
- and
- one or more surface additives applied to a surface of the toner particles, the one or more surface additives comprising titania nanotubes or mixtures of titania nanotubes and titania nanosheets, wherein the titania nanotubes have an average particle diameter of from about from about 5 nm to about 100 nm.
(canceled)
A toner composition comprising:
- toner particles comprising a resin and a colorant;
- and
- one or more surface additives applied to a surface of the toner particles, the one or more surface additives comprising titania nanotubes.
A developer comprising:
- a toner composition;
- and
- a toner carrier, the toner carrier comprising
- a carrier core, and
- a carrier coating disposed over the carrier core, wherein the toner composition comprises
- toner particles comprising a resin and a colorant, and
- one or more surface additives applied to a surface of the toner particles, the one or more surface additives comprising titania nanotubes or mixtures of titania nanotubes and titania nanosheets, wherein the titania nanotubes have an average particle diameter of from about from about 5 nm to about 100 nm.
