Abstract
In a dry process developing apparatus, a toner recirculating and agitating device includes a regulator member located between a magnet brush forming member and a doctor blade to face the periphery of a developing sleeve at a predetermined spacing therefrom. This spacing is progressively reduced toward the doctor blade to increase the force which tends to recirculate the toner through a predetermined path.
