    摘要: An ink jet recording apparatus includes a recording head for performing recording by discharging ink by forming a bubble by applying thermal energy to a heat acting portion of an ink holding portion of the recording head. Thermal energy is generated in the recording head and a cap sealingly caps a discharge opening forming surface of the recording head. Ink is sucked from the cap and positive recovery is effected so that 10.sup.4 or more times of preliminary discharges are performed toward the cap which is detached from the recording head, by supplying energy greater than energy at a recording condition by predetermined multiples of a minimum energy E.sub.o required for generating the bubble, and for causing the ink to be sucked in the cap that is open to atmosphere.

    摘要: A recording head having a plurality of recording elements can operate in a first recording mode for recording a desired image by performing a single scan operation on a predetermined region on a recording medium, and a second recording mode for recording a desired image by recording a thin image a plurality of number of times in a plurality of scan operations on the predetermined region. The scan speed in the second recording mode is set to be higher than that in the first recording mode. For example, when the scan speed in the second recording mode is N times that in the first recording mode, the driving operation of the plurality of recording elements is controlled to obtain a dot pattern in which the minimum dot distance in the scan direction in the second recording mode is N times or more that in the first recording mode. Image quality can be improved without decreasing the throughput.
