Ink jet recording apparatus

An ink jet recording apparatus comprising:

• a recording head configured to record on a recording medium and including a plurality of element arrays, wherein each element array includes a plurality of recording elements that are arrayed in a first direction and used for discharge ink for forming pixels on a recording medium, and wherein each element array is divided into a plurality of groups where each group includes a plurality of recording elements being continuously arranged and assigned to different driving blocks for driving the recording elements;
• a conveyance unit configured to convey the recording medium in a second direction intersecting the first direction;
• and
• a drive control unit configured to control driving of the plurality of recording elements of the plurality of element arrays such that the plurality of recording elements in each group of the respective driving blocks are allowed to be driven in order and at a predetermined time interval between the respective driving blocks,
• wherein a number of the element arrays is equal to or larger than a number of recoding elements in a group, and
• wherein the driving control unit controls driving of the plurality of recording elements so that the recording head is capable of recording pixels based on recording data for one column extending in the first direction using the plurality of element arrays within an area of the recording medium corresponding to conveyance width of a recording medium in the second direction conveyed by the conveyance unit within the predetermined time interval.
