Inkjet recording head

An inkjet recording head for ejecting ink, comprising:

• a plurality of sidewalls to form a plurality of ink channels separated by the plurality of sidewalls, the plurality of sidewalls comprising at least partially a piezoelectric material;
• a bottom plate to form a bottom face of the plurality of ink channels, the bottom plate comprising a piezoelectric material;
• and
• a plurality of electrodes formed on the plurality of side walls, for being applied an electric voltage to cause pressure change in the plurality of ink channels by shear deformation of the plurality of sidewalls, and to eject the ink in the plurality of ink channels;
• wherein all of the plurality of ink channels are divided into two or more groups of ink channels, where a group of ink channels is composed of ink channels between which at least one of the plurality of ink channels is sandwiched;
• wherein an ink ejection operation is performed successively in a time-sharing mode for each of the group of ink channels, while satisfying the condition of
• |CTC+CTE|≦10 (%);
• where a crosstalk between ink channels in one group of ink channels due to a compliance ratio of the plurality of sidewalls to the ink in the plurality of ink channel is CTC;
• and a crosstalk between ink channels in one group of ink channels due to a leak of electric field caused by electric voltage applied to the plurality of electrodes is CTE.
