Abstract
A developing device including a holding body, a supply unit, a filling portion, a closing portion, and a duct portion is provided. The holding body holds a developer. The agitating unit agitates the developer. The supply unit supplies the developer that flows in from the agitating unit to the holding body. The filling portion is provided above the agitating unit and filled with the developer. The closing portion closes a lower portion of the filling portion, and causes the developer to drop from the filling portion into the agitating unit in a case where the closing portion is removed. The duct portion connects a space in the filling portion and a portion above the holding body.
