ABSTRACT:
An ink jet head includes an elongated ink supply port extending in a longitudinal direction and a plurality of head groups arranged in a transverse direction crossing with the longitudinal direction. A first array of ink ejection outlets is disposed along one lateral side of an ink supply port, and second and third arrays of ink ejection outlets are disposed along the other lateral side of the ink supply port, wherein widths L2, measured in the longitudinal direction, of partition walls for the first array of the ink ejection outlets are larger than widths L1, measured in the longitudinal direction, of partition walls of the second and third arrays of the ink ejection outlets. The ink jet head further includes a sealing tape for protecting the ejection outlets, the sealing tape being peelable in a direction from the second or third array toward the first array.
