LIQUID EJECTOR AND EJECTING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent degradation of image quality due to uneven density or a white streak. SOLUTION: A pair of heating resistors 102a and 102b arranged side by side in the substantially same direction as the traveling direction of a recording sheet are fed with power of different magnitude or fed with power while shifting the timing. Ejecting direction of an ink liquid drop i is substantially aligned with the traveling direction of a recording sheet by varying power supply periodically. Since ejecting direction can be varied periodically, ink drops adjacent in the traveling direction of the recording sheet at the shooting point of the ink drop i on the recording sheet compensate the boundaries each other thus preventing a white streak in the direction substantially perpendicular to the traveling direction of the recording sheet or uneven density of color.
