摘要： PROBLEM TO BE SOLVED: To prevent deterioration of image due to crosstalk between adjacent electrodes. SOLUTION: A plurality of ink ejection members 12 are arranged, at a predetermined pitch, in the direction traversing the recording medium carrying passage on the insulating head substrate 10 of a recording head while directing the forward end toward the common electrode 6 side. A predetermined positional shift is imparted to every other ink ejection members 12 in the carrying direction of a recording medium 7. The timing for applying a voltage to the recording electrode corresponding to each ink ejection member 12 is shifted such that ink is ejected alternately from even ink ejection member 12 and odd ink ejection member 12.

摘要： PROBLEM TO BE SOLVED: To prevent ink from adhering to the forward end of an ejection electrode by circulating the ink and cleaning the forward end of the ejection electrode periodically. SOLUTION: Ink liquid level is increased periodically until the forward end of a recording electrode is wetted and, under a state where adhering matters can be separated easily from the forward end of the recording electrode, a voltage is applied to the recording electrode ender to eject ink thus removing the adhering matters. An ink recovery member is located to avoid a recording medium carrying passage 8. In case of a scan type head, a recording head 2 is shifted to a position facing the ink recovery member when printing is not conducted and, after ink supply to an ink ejecting part 5 is increased, ink is ejected toward the ink recovery member at that position. In case of line type head, the recording head 2 is retracted when printing is not conducted and then the ink recovery member is shifted between the recording medium carrying passage 8 and the recording head 2. Thereafter, ink supply to an ink ejecting part 5 is increased and ink is ejected toward the ink recovery member at that position.

摘要： PROBLEM TO BE SOLVED: To perform recording with high fineness and high gradation at a high speed. SOLUTION: When an electric field in a cohesion region 220 is applied to a tip of a discharge electrode, spherical pigment aggregates fly from the tip of the discharge electrode. In this case, a period of ink discharge is relatively long, but fine pixels can be formed on a recording medium because no excessive charged-pigment particles fly from the tip of the discharge electrode. When an electric field in a condensation region 222 is applied to the tip of the discharge electrode, hemispherical or thick-walled shell-like pigment aggregates fly from the tip of the discharge electrode. In this case, an ink solvent containing charged-pigment particles also flies together with the hemispherical or the thick-walled shell-like pigment aggregates and, accordingly, pixels having density higher that of the pixels formed in the case where the electric field in the cohesion region 220 is applied, can be recorded at a high speed. Such an electric field in the condensation region 222 is suitable for solid recording.

摘要： PROBLEM TO BE SOLVED: To realize high speed printing while enhancing concentration efficiency, circulation efficiency and cleaning performance of ink color material of an ink circulation, electrostatic ink jet recorder where coloring material in an ink channel is concentrated through electrophoresis to a flying electrode and flied electrostatically toward a recording medium by an electric field formed between the flying electrode and a counter electrode. SOLUTION: The flying electrode 17 and the electrophoretic electrode 18 of a recording head 11 are disposed oppositely through an ink channel 15. The ink circulation inlet and outlet of the ink channel made in the recording head 11 are made in the wall face thereof where the flying electrode 17 and the electrophoretic electrode 18 are not formed. Upon finishing printing, a coloring material 16 aggregated to the flying electrode 17 is scattered and low concentration ink is circulated to clean the flying electrode 17. High speed printing is carried out by arranging a large number of recording heads 11 in parallel.
