Abstract
A developing device including a first transport path in which the developer to be supplied to the development-region passing body is transported at least in a first transport direction; a second transport path in which the developer to be sent to the first transport path is transported at least in a second transport direction; and a first connection portion through which a portion of the first transport path positioned short of a first-transport-direction-downstream end of the first transport path and a portion of the second transport path positioned short of a second transport-direction-upstream end of the second transport path are connected to one another. A first transport member in the first transport path has a helical reverse-transport blade that reverse-transports the developer in a reverse direction reverse to the first transport provided adjacent to the first connection portion.
