DEVELOPMENT DEVICE, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS

摘要

A development device includes a toner carrier having a plurality of long outside electrodes provided at intervals in a first predetermined depth position from a toner carrying surface, and a longitudinal direction of each outside electrode crossing a toner carrying direction, an inside electrode provided at least in a portion between the long outside electrodes in a second predetermined depth position deeper than the first predetermined depth, and an insulation layer between a layer having the outside electrodes and a layer having the inside electrode; and a voltage applier configured to apply a voltage which hops toners on the toner carrying surface to the inside electrode and the outside electrodes.
