Image forming apparatus incorporating image forming device and cooling device therein

An image forming apparatus, comprising:

• a housing;
• an image forming device in the housing, the image forming device configured to form an image on a recording medium;
• a cooler configured to cool the image forming device;
• a temperature detector configured to detect a temperature around the housing;
• and
• a controller including a memory, the controller configured to,
• generate a counter value during a driving period of the image forming device, the memory configured to store the counter value,
• drive the cooler based on the detected temperature such that the controller is configured to (i) drive the cooler independent of the counter value when the detected temperature is greater than a reference temperature, and (ii) drive the cooler dependent on the counter value when the detected temperature is lower than the reference temperature, and
• control driving the image forming device independent of the counter value to a driving speed when the detected temperature is lower than the reference temperature.
