Title: Developer conveying device and image-forming apparatus with electrodes for conveying charged developer

Abstract: A developer conveying device includes a first guide member, a second guide member, and a plurality of electrodes arranged on the first guide member and the second guide member. The first guide member forms a first section of a conveying path of a charged developer. The second guide member forms a second section of the conveying path which continues from the first section of the conveying path. The plurality of electrodes generate a traveling wave electric field that conveys the charged developer along the conveying path. A following rate at which the developer follows travel of the traveling wave electric field in the second section is different from the following rate in the first section.
