<P>PROBLEM TO BE SOLVED: To provide a developer electric field transport device capable of smoothly conveying developer in a predetermined direction by a progressive wave, and to provide a developer supply device and an image forming apparatus that is equipped with the developer electric field transport device. <P>SOLUTION: A plurality of feeder electrodes 133a, the longitudinal directions of which intersect a sub-scanning direction, are arranged in the sub-scanning direction. A transport electrode power feed wiring section 137 is connected to the root 133a 1 of the transport electrode 133a, which is the lengthwise one end. The toner transport guide member 136 is disposed so as to define the range, within which toner is conveyed by the transport electrode 133a. The toner transport guide member 136 is disposed further inside in the main scanning direction than the root section 133a1 and leading end section 133a2, which are both the end sections of the transport electrode 133a, and the transport electrode power supply wiring section 137, and the toner transport guide member 136 is configured so that toner is restrained from leaking out. <P>COPYRIGHT: (C)2008,JPO&INPIT |
