ABSTRACT:
A print head can improve an ink refill speed to reduce the time from the end of one ejection of ink droplets until the beginning of a next ejection of ink droplets and maintain the high quality of images obtained by printing. An ink jet print head has an ejection port portion including a first ejection port portion communicating with atmosphere, and a second ejection port portion having a cross-section which extends in a direction orthogonal to an ejecting direction and which is larger than that of the first ejection port portion. The second ejection port portion is formed between a bubbling chamber and the first ejection port portion. In the ink jet print head, an ejection port portion first axis is located away from an ejection port portion second axis.
