Abstract: A developing device includes a first agitating member and a second agitating member. Each of the first and second agitating members includes a screw having a helical portion formed helically so as to define a hollow portion, and a plurality of ribs formed on the helical portion in the longitudinal direction of the screw. On at least one of the first and second agitating members, there is disposed a paddle opposed to the communicating portion on a downstream side in a transport direction of the developing powder. The paddle has a flat surface in a direction perpendicular to the longitudinal direction, and a width of a distal end of the paddle is smaller than a width of a proximal end of the paddle disposed to the agitating member in a plan view.

Abstract: An image forming apparatus includes a developing device, a toner reservoir, a toner replenishing device, a development driving device, a developer amount detecting sensor, and a controller. The developing device includes a developing container, a first stirring-conveyance member, a second stirring-conveyance member, and a developer carrier. The developing container includes a first conveyance chamber and a second conveyance chamber disposed above the first conveyance chamber. The developer amount detecting sensor detects an amount of developer that falls from the second conveyance chamber to the vicinity of a toner replenishing port in the first conveyance chamber. The controller controls the driving of the toner replenishing device or the driving of the development driving device based on a result of detection performed by the developer amount detecting sensor, and thereby keeps a replenished-toner concentration in the developer substantially constant in the vicinity of the toner replenishing port.

Abstract: A developing device has a developer carrier, a regulating member, a regulating pole, and a magnetic pole generation member. The regulating member has a magnetic body for regulating the thickness of developer on the surface of the developer carrier. The regulating pole is arranged inside the developer carrier to face the regulating member. The magnetic pole generation member is arranged upstream of the regulating member in the developer carrier rotation direction, and has a magnet for generating, at an end portion of the regulating member, a magnetic pole of a polarity different from that of the regulating pole. The regulating member has, in its side face, a depressed portion having an inner face with an arc-shaped cross-section. The magnetic pole generation member is cylindrical, with a radius substantially equal to that of the inner face of the depressed portion, and is rotatable while staying fitted in the depressed portion.
