Carrier comprised of a core, a number of the pores thereof containing a polymer, and thereover a coating.

Carrier

A process for the preparation of microsynthetic carrier comprising the melting of a mixture of binder resin, magnetic component, colorant and optionally charge control additive, thereby forming a polymer melt, and mixing said mixture in a melt mixing device, cooling and pelletizing said mixture, and thereafter grinding and classifying said pellets.

Carrier pelletizing processes

A carrier comprised of a carrier core, optional polymer coating, and fluorosilanated pigment coating.

Carrier particles with halosilanated pigments

Carrier coating processes

Carrier comprised of a hard magnetic core, the pores thereof containing polymer, and thereover s coating.

A composition comprised of a core and thereover a mixture of a first and second polymer, and wherein said first polymer contains a conductive component, and said second polymer contains copper iodide, and wherein the coating weight percent for said first and said second polymer is from about 5 to about 25.

Coated carriers

A toner composition comprised of a mixture of first toner with wax, and second toner free of wax, and wherein said first and said second toner contain binder, and said first toner with wax contains colorant.

Toner compositions

A carrier comprising core particles with a coating thereover comprised of at least one polymer, a conductive colorant, and a stabilizer compound.

Carrier composition and processes thereof

Conductive polymeric particles can be formed by mixing a monomer, carbon black and a block copolymer, wherein the block copolymer contains an A block that is miscible with said monomer and a B block that anchors to the surface of the carbon black, such as polystyrene or a derivative of polystyrene. A polymerization initiator is added to the mixture and bulk polymerization is effected until about 5 to about 30 weight percent of the monomer has been polymerized. This partially polymerized product is then dispersed in water and further polymerized.

A composition comprised of a core and thereover a mixture of a first and second polymer, and wherein said first polymer contains a conductive component, and said second polymer contains copper iodide.

Coated carrier particles

A conductive carrier composition comprised of a core with a coating thereover comprised of a mixture of first and second polymers, and wherein the first polymer contains a conductive component, and the second polymer contains a metal oxide.

Conductive developer compositions with coated carrier particles

A process for the preparation of conductive polymeric particles with linear and crosslinked portions, which comprises mixing a monomer with at least one conductive filler, solvent, at least one polymerization initiator, and a chain transfer component; effecting solution polymerization by heating until from about 80 to about 100 weight percent of the monomer has been polymerized; drying the mixture by removing the solvent to yield an intimate blend of polymer with conductive filler; dispersing the aforementioned blend of polymer and conductive filler in at least one monomer with at least one polymerization initiator, a crosslinking agent and a chain transfer agent to form an organic phase; dispersing the resulting organic phase mixture in water containing a stabilizing component to obtain a suspension of particles with an average volume diameter of from about 0.05 to about 5 microns in water; polymerizing the resulting suspension by heating; and subsequently optionally washing and drying the polymeric product.
