Abstract
A developing device includes a first transport path and a second transport path. In the first transport path, a developer containing toner and a magnetic material is transported in the axial direction of a first transport member that opposes a developer holding element by rotation of the first transport member. The second transport path includes plural flow paths that extend along the axial direction, and plural second transport members provided in the plural flow paths to transport the developer. The plural flow paths each have a length in the axial direction that is shorter than the length of the first transport path in the axial direction. Respective end portions of the first and second transport path are connected such that the developer which has flowed into the second transport path from one end of the first transport path flows into the other end of the first transport path.
