Abstract
A developing device include: a toner carrier that is arranged oppositely to an image carrier; a toner-flying electrode member spaced apart from the toner carrier; and an oscillating electric field generating power source that connects the toner-flying electrode member and the toner carrier, and generates an oscillating electric field which causes the toner to fly from the toner carrier. The toner-flying electrode member includes a conductive member that extends at least along a rotational axis direction of the toner carrier; an insulating coating layer that applies insulating coating continuously to a conductive member surface located on a toner carrier side; and an exposed portion where the conductive member surface adjacent to the insulating coating layer and located on an image carrier side is exposed.
