Abstract
A developing device includes a housing including a container that holds a developer containing toner and a magnetic carrier, a feed port member that allows toner or a magnetic carrier to pass therethrough to be fed into the container, a rotary member spaced apart by a gap from a surrounding portion of the housing including the feed port member, the rotary member transporting the developer while holding the developer on an outer circumferential surface of the rotary member to cover the gap when a developer level of the developer inside the container exceeds a reference level, and a developer-level adjusting magnetic pole that holds the developer and that is located at the same level as an end of the gap located downstream from the feed port member in a rotation direction of the rotary member or located downstream from the end of the gap in the rotation direction.
