Claim:
1. A developing device comprising: a developer carrier configured to rotate while carrying a developer on an outer circumferential surface thereof; a thickness restricting portion disposed spaced apart from the developer carrier, and configured to restrict a thickness of the developer carried by the developer carrier; and an airflow rotor configured to rotate 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, thereby to generate airflow in a space between the airflow rotor and the upper surface of the thickness restricting portion, wherein the airflow rotor is a conductor, and a bias voltage of the same potential as that of the developer carrier and the thickness restricting portion is applied to the airflow rotor.
