Patent ID: 6851779

Claim:
A liquid ejecting apparatus for ejecting liquid using a bubble, comprising: a recording head comprising: a plurality of ejection outlets for ejecting the liquid; a plurality of heat generating elements, provided for each of said ejection outlets, for generating heat to form a bubble, each of said heat generating elements having an area; a bubble generating region where the bubbles are generated in the liquid by activation of said heat generating elements; and a movable member, provided for each of said ejection outlets, which is disposed faced to said bubble generating region and which has a fulcrum and a free end located downstream of the fulcrum relative to a direction of flow of the liquid, each of said movable members being displaceable between a first position and a second position farther from the bubble generating region than the first position, wherein a portion of each of said movable members facing center points of the areas of corresponding heat generating elements is displaceable; and control means for controlling said heat generating elements in such a manner as to generate heat to displace said movable members without ejecting the ink, and to generate heat again before said movable members have returned to their original positions.
