摘要

Disclosed are a carrier for developing electrostatic images, the carrier comprising a core and a coating on the core, the coating being formed from a copolymer comprising about 50 to about 90 mole% of vinylidene fluoride, about 5 to about 45 mole% of tetrafluoroethylene and about 1 to about 30 mole% of a fluorine-containing unsaturated polymerizable compound; and a carrier for developing electrostatic images, the carrier comprising a core and a coating on the core, the coating being formed from a copolymer comprising about 50 to about 90 mole% of vinylidene fluoride and about 50 to about 10 mole% of at least one fluorine-containing unsaturated polymerizable compound selected from the group consisting of trifluorochloroethylene, 1,1-dihydrohexafluoroisobutene, hexafluoropropylene, perfluoro(alkyl vinyl ether), trifluoroethylene and hexafluoroacetone.
