INKJET RECORDING HEAD AND INKJET RECORDER

摘要

PROBLEM TO BE SOLVED: To provide an inkjet recording head and an inkjet recorder capable of always obtaining a good printed result at a boundary section of a recorded region formed by each scanning for recording even in the inkjet recorder wherein the using range of a nozzle array is varied based on a recording condition. SOLUTION: In this inkjet recording head, an arrangement interval of ejection nozzles of an ejection nozzle array at a part is greater than that at the other part and a recording width in the paper feeding direction in a region recorded by one time of scanning for recording is made to be greater than an amount of a moved recording medium by one time of paper feeding. As the nozzles are provided such that the interval of the nozzles of only the part which is used in any recording condition is greater than that of the other, the recording width by one scanning for recording is always greater than the paper feeding width by a predetermined amount so that the boundary sections of the recorded regions formed by the respective scanning for recording are overlapped with each other by a predetermined amount.
