Abstract:
1. A recording apparatus comprising: a recording head that comprises: a driving circuit that selectively supplies to the actuator a discharge driving signal, which includes at least one of discharge pulse signals and is used to drive the actuator so as to discharge the liquid from the discharge port, and a non-discharge driving signal, which includes at least one of non-discharge pulse signals and is used to drive the actuator so as not to discharge the liquid from the discharge port, a transport unit that transports a recording medium to a position facing the recording head; an image recording control unit that controls the actuator to discharge the liquid onto the recording medium transported by the transport unit on the basis of image data; a signal number calculating unit that calculates a number of non-discharge driving signals supplied from the driving circuit to the actuator on the basis of the image data; and a non-discharge driving control unit that controls the driving circuit to supply the number of non-discharge driving signals calculated by the signal number calculating unit, wherein the signal number calculating unit calculates the number of non-discharge driving signals such that the sum of a corrected number of discharge pulse signals and a total number of non-discharge pulse signals supplied to the actuator within a predetermined period is equal to a predetermined value, the corrected number of discharge pulse signals being a number which is obtained by correcting a total number of discharge pulse signals supplied to the actuator within the predetermined period to be smaller than the total number of discharge pulse signals.
