ABSTRACT:
Provided is an image forming apparatus equipped with a developing apparatus using a developer containing toner and carrier, in which, by taking into account a change in the toner density of a replenishment agent, the supply of replenishment agent to the developing apparatus is effected with high accuracy, thereby forming a stable image involving no scattering of toner. In the image forming apparatus including a replenishment agent supply device that supplies a replenishment agent containing the toner and the carrier to the developing apparatus, the replenishment agent is gradually supplied to the developing apparatus from the replenishment agent supply device while the developer is gradually discharged in correspondence therewith from a developer discharging port, and the replenishment agent supply device has a first toner density detecting device for detecting the toner density of the replenishment agent.
