Abstract: An ink jet recording apparatus, equipped with an ink jet head, comprises a device for vibrating a meniscus more than once in response to each print signal when the ink is not discharged. Further, in the apparatus, the meniscus is vibrated more than once at a repetition frequency higher than an audible frequency (20 Hz to 20 kHz) so that the ink may not be discharged. In addition, a meniscus vibration driving signal is set to a burst signal while the recording is performed.
