Abstract
A developing device includes a developer carrier to carry a developer, a conveyance path to circulate the developer and supply the developer to the developer carrier, a discharge path extending from the conveyance path and including a discharge port to discharge a portion of the developer, as excess developer, and a valve body provided between the conveyance path and the discharge port. The valve body includes an inlet side oriented toward the conveyance path and an outlet side disposed opposite the inlet side to allow a passage of the excess developer from the conveyance path through the valve body toward the discharge port, when a pressure applied to the inlet side is greater than a pressure threshold value.
