ABSTRACT:
A developing device for an image forming apparatus and capable of automatically controlling the toner content of a developer is disclosed. Even when the toner content of the developer deposited on a developer carrier and being conveyed toward a developing position becomes irregular due to some cause, the developer is prevented from remaining at the developing position. This guarantees a desired developing position despite the automatic toner content control. In addition, the toner content of the developer is prevented from increasing at portions adjoining the opposite ends of the developer carrier.
