摘要 |
An ink jet recording apparatus records using a recording head. The head comprises a plurality of discharge ports for discharging ink, a common liquid chamber for supplying ink to the plurality of discharge ports, and a plurality of discharge elements for causing ink to be discharged from the plurality of discharge ports. The apparatus further comprises driving elements for substantially simultaneously driving said discharge elements corresponding to a first plurality of discharge ports which are not adjacent to each other, among said plurality of discharge ports, and for driving said discharge elements corresponding to a second plurality of discharge ports which are respectively adjacent to said first plurality of discharge ports, not simultaneously with said discharge elements corresponding to said first plurality of discharge ports, but at predetermined intervals within a drive period.
