A boundary nozzle which is contained in a block that has not been driven and is situated at the boundary with a driving block that is driven prior to the block containing the boundary nozzle contains a second stopper which has a length in a liquid flow direction longer than that of a first stopper contained in a driving nozzle in the driving block that is driven prior. A near-boundary nozzle adjacent to the boundary nozzle has a third stopper which has a length in a liquid flow direction longer than that of the first stopper but shorter than the second stopper. Thus, recording irregularities owing to meniscus regression are suppressed.
