摘要： In a recording apparatus provided with a plurality of discharging ports for discharging ink, and discharging elements for discharging ink upon application of electrical pulses, the volume of ink droplets discharged from each of the discharging ports is caused to vary due to the properties of each discharging port. This variation results in a conspicuous unevenness in recording. The present invention provides a method for making such recording unevenness due to the properties of each discharging port inconspicuous by varying the volume of ink droplets discharged from each of the plural discharging ports at random. Also, the present invention provides a technique in which the volume of discharging ink droplets is varied at random by use of a specific ink in order to make the recording unevenness inconspicuous.

摘要： An ink jet recording apparatus of the present invention has an ink jet recording head having an orifice from which an ink drop is ejected and an energy generation means for ejecting an ink fluid in the orifice. A first electrode is formed in the orifice and is connected electrically to the ink fluid. A second electrode is formed in an opposite position to the orifice with a designated distance from the orifice. A voltage controller applies a first voltage during a time period from a time when an ink fluid is ejected from the orifice to a time when the ink fluid is separated in 2 or more ink drops during traveling, and immediately after applying the first voltage, applies a second voltage which has an identical polarity to a polarity of the first voltage and has an absolute value less than an absolute value of the first voltage.

摘要： In an ink jet recording apparatus in which a filter is placed in an ink supply route, when an ink flow is formed in the ink supply route by ink ejection during recording operations and so on, a valve does not contact firmly to the filter, but when an ejection recovery operation is performed and an ink flow velocity increases, the valve contacts firmly to the filter and covers up a part of the filter. With this structure and operation, the effective cross-section area of the filter decreases and hence, a given quantity of pressure difference is produced between the upstream side and the downstream side of the filter. As a result, bubbles unable to pass through the filter at recording operations can pass through the filter when ejection recovery operations are performed.
