Abstract
An image forming apparatus includes a main body housing, a first cartridge to store first developer, a second cartridge to store second developer, a first temperature sensor to detect an inside temperature as a temperature inside the main body housing, and a controller configured to calculate a first control temperature corresponding to the first cartridge, using the detected inside temperature and a first coefficient to be multiplied by the inside temperature, calculate a second control temperature corresponding to the second cartridge, using the detected inside temperature and a second coefficient to be multiplied by the inside temperature, the second coefficient being different from the first coefficient, and perform cooling control to cool an inside of the main body housing when at least one selected from the first control temperature and the second control temperature is higher than a particular threshold.
