PROBLEM TO BE SOLVED: To provide an ink jet recording head in which refill frequency can be maximized while sustaining the linearity of image even in case of time sharing drive and throughput of a printer can be enhanced. SOLUTION: In an ink jet recording head having a plurality of ink ejection openings 3 and heaters 2 disposed oppositely thereto in order to generate thermal energy being used for ejecting ink wherein they are sectioned into a plurality of blocks being driven sequentially in the same drive period while sharing the time, the plurality of heaters 2 are arranged substantially linearly and the ink ejection openings 3 are arranged in such a projection relationship as corresponding to the time sharing driving order while being shifted from the heaters 2. Alternatively, the plurality of ink ejection openings 3 are arranged substantially linearly and the heaters 2 are arranged in such a projection relationship as corresponding to the time sharing driving order while being shifted from the ink ejection openings 3.
