Ink jet recording method and apparatus having drop size control by using plural control electrodes
摘要：
An ink jet recording apparatus is provided with an ink jet recording head which includes at least one nozzle for ejecting ink, a heating layer, and a ground electrode and a plurality of control electrodes electrically connected to the heating layer, and a thermal energy action part, formed in the heating layer in correspondence with the nozzle, for heating the ink and causing a state transition so as to eject the ink from the nozzle when a voltage is applied across at least one pair of the ground electrode and the control electrode. The ground electrode electrically connects to the heating layer within a region of the thermal energy action part, and the control electrodes electrically connects to the heating layer outside the region of the thermal energy action part.
摘要（中）：

喷墨记录装置设置有喷墨记录头，该喷墨记录头包括用于喷射油墨的至少一个喷嘴，加热层和接地电极以及电连接到加热层的多个控制电极，以及热能作用部分 形成在与喷嘴对应的加热层中，用于加热油墨并引起状态转变，以便当在至少一对接地电极和控制电极之间施加电压时从喷嘴喷出墨。 接地电极在热能作用部分的区域内电连接到加热层，并且控制电极电连接到热能作用部分的区域外的加热层。
