摘要：
A developing device is provided. The developing device includes a developer carrier, a regulator, a first developer storing chamber, a plurality of conveyers disposed within the first developer storing chamber, a second developer storing chamber in communication with the first developer storing chamber, and a supply member disposed within the second developer storing chamber. The developer carrier carries developer on its surface and supplies developer to a latent image carrier carrying a latent image. The regulator regulates the thickness of developer on the surface of the developer carrier. The first developer storing chamber stores developer separated from the developer carrier by the regulator and is to be supplied with fresh developer. Each of the plurality of conveyers coveys developer in a different conveyance direction. The second developer storing chamber is to be supplied with developer from the first developer storing chamber. The supply member supplies developer to the developer carrier.
