The developing device provided in accordance with the invention includes a developer layer thickness controlling member for controlling the thickness of the developer through the developer carrier. The layer thickness controlling member is brought into press contact with the developer carrier downstream in the moving direction of the developer carrier. A first sealing member (48,49) is provided for cutting off the developer moving to both ends of the developer carrier. A second sealing member (50,51) is provided for shielding the junction of the developer carrier, the first sealing member, and the layer thickness controlling member. Finally, a sheet-shaped elastic body is provided for cutting off the developer which moves to the ends of the developer carrier.
