Abstract
An image forming apparatus of an exemplary embodiment includes a temperature sensor, a developing unit, a supply unit, and a control unit. The temperature sensor detects a temperature. The developing unit supplies developer to an image carrier and performs development. The supply unit contains developer and supplies the contained developer to the developing unit. The control unit executes developer replacement processing including discharging the developer from the developing unit and supplying the developer contained in the supply unit to the developing unit based on a first ratio which a ratio of a developer supply time during which the supply unit performs supply of the developer for the developing unit and a drive time during which the developing unit is driven and a threshold value obtained based on a detected temperature of a temperature sensor.
