Ink jet recording apparatus

摘要

An ink jet recording apparatus includes a recording head and a driving unit. The recording head includes a plurality of element columns. Each element column includes a plurality of recording elements arrayed in a first direction to discharge ink, and is divided into a plurality of groups including a plurality of continuous recording elements. The driving unit drives the recording head and execute control so that the plurality of recording elements in each group is driven in order at a specific time interval. A number of the element columns is equal to or larger than a number of recoding elements in a group. The driving unit controls driving of the plurality of element columns so that recorded data of one column is recorded within a conveyance width of a recording medium to be conveyed within the specific time interval.
