2. Description of the Related Art
Non-impact recording methods have recently gained attention since the noise created from the methods during recording is so little that the noise is almost unnoticeable. Among such methods, the so-called inkjet recording method is known as an effective recording method which records with high speed and requires no special fixing process when recording to plain paper. Various types of inkjet recording methods have been proposed and improved. Some have been introduced to the market as actual products, while others are still being developed for practical use.
The inkjet recording method records by ejecting droplets of recording liquid (so-called ink) onto a recording medium. Various types of inkjet recording methods are described below. The various types of inkjet recording methods can be classified according to methods for creating the droplets, or methods for controlling the flight direction of the droplets.
In the prior art, for example in U.S. Pat. No. 3,060,429, a Tele-type method, which is an electrostatic attraction type method, is known as a method that creates droplets of ink by electrostatic attraction, controls the droplets by controlling an electric field according to recording signals, and allows the droplets to selectively adhere to a recording medium, to thereby achieve recording.
Furthermore, U.S. Pat. Nos. 3,596,275 and 3,298,030) disclose a Sweet type method which is a continuous stream and charge-controlled type method. The method creates droplets of recording liquid having electric charges thereof controlled by a continuous vibration method, and allows the electrically charged controlled droplets of the recording liquid to fly between deflection-electrodes applied with a uniform electric field, to thereby record to a recording medium.
As for another example, U.S. Pat. No. 3,416,153 discloses a Hertz type method which applies an electric field to a discharge port and a ring-like electrode, and creates a mist of droplets of recording liquid with use of a continuous vibration method, to thereby provide a recording image on a recording medium. That is, the strength of the electric field applied between the discharge port and the electrode is modulated according to recording signals, to thereby create a gradation

 Non - impact recording methods have recently gained attention since the noise make from the methods during recording is so little that the randomness is almost unnoticeable. Among such method, the so - call inkjet recording method is known as an effective recording method which records with high focal ratio and requires no special fixing process when recording to plain paper. Various types of inkjet recording methods have been proposed and improved. Some have been introduced to the market as actual products, while others are still being developed for hardheaded use. 
 The inkjet recording method criminal record by eject droplets of recording liquid (so - call ink) onto a recording medium. Various types of inkjet recording methods are trace below. The various types of inkjet recording methods can be classified according to methods for produce the droplets, or methods for controlling the flight management of the droplet. 
 In the anterior artwork, for example in U.S. Pat. No. 3,060,429, a Tele - type method, which is an electrostatic attraction type method, is known as a method acting that creates droplet of ink by electrostatic attraction, controls the droplets by controlling an electric field accord to recording signals, and allow the droplets to selectively cling to a recording medium, to thereby achieve recording. 
 Furthermore, U.S. Pat. Nos. 3,596,275 and 3,298,030) unwrap a Sweet type method which is a continuous flow and charge - controlled character method. The method creates droplets of recording liquid having electric charges thereof controlled by a continuous vibration method, and allows the electrically charge controlled droplets of the recording liquid to vanish between deflection - electrodes apply with a uniform electric field, to thereby record to a recording medium. 
 As for another example, U.S. Pat. No. 3,416,153 discloses a Hertz type method which applies an electric battlefield to a dismissal larboard and a ring - like electrode, and creates a mist of droplets of recording liquid with use of a continuous vibration method acting, to thereby provide a recording image on a recording medium. That is, the strength of the electric field applied between the discharge port and the electrode is modulated according to record signals, to thereby create a gradation
