A method of forming toner particles having surface particles attached thereto includes the steps of aggregating a material of at least one binder material and at least one colorant to produce toner particles, following aggregation, forming a mixture of the surface particles and the toner particles, and subjecting the mixture to a temperature above the glass transition temperature of the toner particles to coalesce the toner particles, whereby the surface particles become at least partially embedded within the surface of the toner particles. Toner particles prepared by such method include a core comprised of at least one binder and at least one colorant, and surface particles at an external surface of the toner particles, wherein at least about 50% of the surface particles are substantially completely covered by a portion of binder and a majority of the surface particles protrude from the toner particle surface a distance of at least 50% of the average particle size of the surface particles.

Surface particle attachment process, and particles made therefrom

An apparatus for removing charged particles from a surface, the surface being capable of movement, including: a conductive brush in contact with the surface, the conductive brush having a first region thereof having a first polarity and a second region having a second polarity; the conductive brush includes a core and conductive fibers attached thereto, the core being electrically segmented into the first region and the second region.

Dual polarity electrostatic brush cleaner

A carrier comprised of a core and thereover a polymer coating, and which coating is generated by the emulsion polymerization of one or more monomers and a surfactant, and wherein said polymer coating is of a diameter of equal to or less than about 100 nanometers.

Carrier compositions

A toner composition includes a binder, a colorant, and surface-treated sol-gel metal oxide particles surface-treated with a treatment agent.

Toner compositions with surface additives

A toner composition includes toner particles formed of a resin and a colorant; and one or more external additives, at least one of the external additives including polymeric particles, applied to a surface of the toner particles. The polymeric particles include a polymer selected from polymethylmethacrylate, modified polymethylmethacrylate, halogenated polymethylmethacrylates, and mixtures thereof.

Polymeric particles as external toner additives

A cleaning blade has a fixed end and a distal cleaning end, with the fixed end maintained in a substantially fixed position. The cleaning blade has a blade cleaning surface arranged for facing a photosensitive element surface of a moving photosensitive element, with the cleaning end arranged to contact and clean the photosensitive element surface. The cleaning blade has a blade temperature. The cleaning blade includes at least one heater for maintaining the blade temperature at a fixed temperature.
