Abstract
A developing device includes a developer carrier, a thickness restricting portion, and an airflow rotor. The developer carrier rotates while carrying a developer on an outer circumferential surface thereof. The thickness restricting portion is disposed spaced apart from the developer carrier, and restricts the thickness of the two-component developer carried by the developer carrier. The airflow rotor is a rotor that rotates in a direction opposite to a rotation direction of the developer carrier, at a position spaced apart from an upper surface of the thickness restricting portion and from the outer circumferential surface of the developer carrier. The airflow rotor generates airflow in a space between the airflow rotor and the upper surface of the thickness restricting portion.
