摘要:
An ink jet recording head comprises ink paths communicated with ink discharge ports for discharging ink, and heat generating portions arranged on the inner wall faces of the ink paths for generating thermal energy utilized for discharging ink from the discharge ports. For this ink jet recording head, liquid-repellent treatment is processed only on the regions that correspond to the heat generating portions of the inner wall faces of the ink paths. With the liquid-repellent treatment processed only on the regions corresponding to the heat generating portions on the inner wall faces of the ink paths, it is made difficult for the refractory substances that may be brought about by the decomposition of colorant or the like contained in ink to be fixed on the regions corresponding to the heat generating portions. As a result, the heat of each heat generating device is transferred to ink evenly to make stable ink discharges obtainable for the provision of recorded images in higher quality.
