Toner bearer, and developing device and image forming apparatus using same |
摘要 |
A toner bearer including an electroconductive substrate; an insulating layer located on the electroconductive substrate; multiple electrodes located on the insulating layer at regular intervals; an outermost layer located on the multiple electrodes; and a voltage applicator to apply a voltage between the electroconductive substrate and the multiple electrodes to form a periodically reversed electric field therebetween so that toner particles on the outermost layer hop, thereby forming a toner cloud above the outermost layer. The insulating layer includes a crosslinked material having a unit obtained from a fluorine-containing resin and a crosslinking agent. The fluorine-containing resin is selected from the group consisting of copolymers having a unit obtained from fluoroethylene having at least three fluorine atoms and a unit obtained from a vinyl ether monomer and copolymers including a unit obtained from tetrafluoroethylene and a unit obtained from a vinyl monomer. |
