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.

Claim (Index 4):
The image forming apparatus according to  claim 2 ,\n wherein the controller keeps the toner replenishing speed constant in a case where the amount of developer detected by the developer amount detecting sensor is larger than the reference value.
