摘要： 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.

摘要： An image forming apparatus includes a latent image forming unit, a developing unit, replenishing unit, and a control unit. The latent image forming unit forms an electrostatic latent image corresponding to an image information signal on an image carrier. The developing unit develops the electrostatic latent image using a two-component developer in which magnetic carriers are mixed with toner to form a visible image. The replenishing unit replenishes the toner to the developing unit. The control unit controls switching between first processing, which includes idling processing for replenishing at least part of residual toner, which is to be replenished to the developing unit and remains without being replenished to the developing unit, to the developing unit and stirring the toner within the developing unit, and second processing, which includes the idling processing and density correction processing for correcting a density of the toner within the developing unit.
