ABSTRACT:
In a development device for containing a developer and developing an electrostatic latent image formed on an image carrier, a supplier supplies fresh developer to the development device. A developer carrier carries the developer to be supplied to the electrostatic latent image formed on the image carrier. A plurality of conveyance members conveys the developer contained in the development device in an axial direction of the development device to form a circulation path. An outlet is provided in a wall of a conveyance path formed by one of the plurality of conveyance members and discharges the developer to an outside of the conveyance path. A discharge conveyance member forms a discharge conveyance path to convey the developer discharged from the outlet in the axial direction of the development device and to discharge the developer to an outside of the development device.
