An ink jet recording head includes a nozzle array and discharge energy generation elements. The nozzles include discharge ports to discharge liquid when recording, pressure chambers to communicate with respective discharge ports, and liquid flow paths to supply liquid to the respective pressure chambers. The discharge energy generation elements apply discharge energy to the pressure chambers to discharge liquid from the nozzles in a predetermined order during time-division driving. Arranging intervals of the liquid flow paths take at least two different values. When a drive timing difference average between the adjacent discharge energy generation elements is calculated by a particular expression, a relationship of D≧Y is satisfied between an interval D and an interval Y in a k-th discharge energy generation element and a k+1-th discharge energy generation element positioned adjacent to the k-th discharge energy generation element. The intervals D and Y represent distances between particular liquid flow paths.
