ABSTRACT:
An ink jet recording apparatus and method for preventing condensation from forming in a recording area having heaters for heating a recording head and a recording medium, a humidity detector for detecting the humidity in the recording area and a controller for controlling the temperature of the heaters in response to the humidity detected by the humidity detector. The controller decreases the temperature difference between the recording head and the recording medium by adjusting the heaters in order to lower the humidity in the recording area when it is higher than a predetermined value. If the humidity in the recording area is not controlled the quality of the recording will be impaired.
