摘要：
An ink jet apparatus has an ink jet head with a heat generating resistance element, which head discharges ink droplets by causing a state change in ink using heat generated by the resistance element, conveying means for conveying a recording medium to be recorded upon in a conveyance direction so that a predetermined recording image is formed on the recording medium by ink droplets from the head, heat exchanging means for exchanging heat with the head, this exchanging means being attached to the side of the head where the element is provided, and heating means for heating the exchanging means, the heating means being part of the heat exchanging means. It also includes a cooling means for cooling the heat exchanging means, temperature detecting means for detecting the temperature of the heat exchanging means, and control means for controlling driving of the heating means and cooling means according to the temperature detected by the temperature detecting means. The head to which the heat exchanging means is attached is joined to the apparatus so that the heat exchanging means is positioned at a downstream side in the conveyance direction of the recording medium.
