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 2):
The image forming apparatus according to  claim 1 ,\n wherein the controller reduces toner replenishing speed, at which the toner is replenished by the toner replenishing device, in stages according as the amount of developer detected by the developer amount detecting sensor becomes increasingly smaller than a reference value.
