摘要： An ink jet recording head comprises a discharge port for discharging ink, two electrothermal converting elements for generating thermal energy utilized for discharging the ink, and an ink flow path provided with the two electrothermal converting elements, at the same time, being conductively connected with the discharge port, and this head has a first discharge mode for discharging liquid droplets from the discharge port when the electrothermal converting element on the side nearer to the discharge port, of the two electrothermal converting elements, receives driving signals to generate the thermal energy, and also, a second discharge mode for discharging liquid droplets from the discharge port in the larger discharge amount than that of the first mode when both of the two electrothermal converting elements receive driving signals to generate the thermal energy. Then, of the two electrothermal converting elements, the length of the electrothermal converting element on the side farther away from the discharge port in the ink discharge direction is made shorter than that of the other electrothermal converting element. With the ink jet recording head thus structured, it is possible to perform higher speed printing in higher image quality and higher gradation.
