Element board for recording head, recording head and recording head control method

The present invention provides a recording head element substrate, a recording head and a method of controlling the recording head. The recording head having: a plurality of recording elements; a shift register for receiving data and recording the recording elements corresponding to the number in a serial manner; holding latch circuit is inputted to said shift register for recording data; and is held in accordance with in recording data of the latch circuit and a signal indicating the period of driving, a driving circuit for selectively driving each recording element. In the recording head, in accordance with the control signal to maintain the state of the latch circuit represents the drive period constituted, it represents a common holding state and the control signal latch circuit during a drive signal to reduce the number of input terminals of the recording head.
