Abstract:
1. A toner bearer comprising: an electroconductive substrate; an insulating layer located on the electroconductive substrate and including at least a crosslinked material having a unit obtained from a fluorine-containing resin and a crosslinking agent, wherein 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; multiple electrodes located on the insulating layer at regular intervals; an outermost layer located on the multiple electrodes and a portion of the insulating layer on which the multiple electrodes are not present; 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.
