PROBLEM TO BE SOLVED: To form an image having a photographic quality. SOLUTION: This ink jet print cartridge comprises an ink supplying source, a plurality of ink ejection chambers 94 defined by a barrier layer 104 formed on a surface and a substrate 88 that has ink ejection elements corresponding to the ink ejection chambers and ejects ink drops each having a predetermined quantity and a predetermined speed. The ink ejection chambers 94 each having an inlet channel 132 with an identical length are arranged at intervals so as to provide a predetermined printing resolution. The ink jet print cartridge further comprises a nozzle member positioned above the barrier layer 104 and an ink channel 132 for connecting the ink supply source to the ink channel 132 such that each of the ink ejection chambers 94 has an ink opening 82, respectively and the openings 82 are aligned to the ink ejection chambers 94. As a result of the above structure, the ink drop having a small quantity can be ejected in a high speed. |
