摘要： PURPOSE:To make responsiveness to a light signal better and to enable recording to be performed at high speed, by a method wherein electrodes connected by a photoconductive insulating material are constructed so as to have parts opposed in a nested state to each other to form a crooked gap. CONSTITUTION:A comb type first common electrode 7 that base end parts of respective high voltage applying electrodes 6 are arranged leaving a specific interval and base end sides thereof are commonly connected is formed on an upper face of base end part of a substrate 5, and optical switches 8... are constructed by respectively connecting the first common electrode 7 and respective high voltage applying electrodes 6 by a photoconductive insulating material 20. Herein, since the electrodes 6, 7 connected via the photoconductive insulating material 20 are constructed so as to have parts 6a, 7a opposed in a nested state to one another to form a zigzag bent gap 21, respective opposed parts of the electrode contributing to photoelectric current can be taken large, and current flows sufficiently. Breaking time of an electric potential is shortened and, as a result, responsiveness to light is elevated. Further, a resistant value of an optical sensor 8 can be easily controlled by changing its shape, and good recording can be performed at high speed.

摘要： PURPOSE:To prevent generation of spark discharge between a recording electrode and a rear electrode by coating at least the tip of the recording electrode with an insulative membrane. CONSTITUTION:The tip of a recording electrode 13 is formed at a position approximately 30mum way back from a ground wedge-shaped end 18 of a substrate 10, and the surface of the recording electrode 13 is coated with an Si3N4 insulative membrane 14 of a thickness of 1,000Angstrom by means of plasma polymerization reaction. Next, a top plate is mounted on the substrate 10 through a spacer and integrally fixed adhesively using an epoxy resin adhesive to form an ink recording head. The preferable retreating distance of the tip of the recording electrode 13 from the end of the substrate is 5-300mum. In addition, the recommendable materials for coating the recording electrode 13 are SiC, SiN, SiO2, TiO2, Al2O3, BN, AlN, etc.

摘要： PURPOSE:To easily impress a pulse to an electrode without complexing the structure of a recording device and to reduce the size of the device by especially constituting a signal voltage impressing means for impressing a recording signal voltage to a recording electrode. CONSTITUTION:When magnetic toner 5 is put into a hopper 6 and a magnet 2 is rotated, the magnetic toner 5 flows out and a magnetic brush is formed close to the magnetic poles of the magnet 2, so that a toner chain 11 is formed on the tip of a recording electrode 3, the tip is allowed to contact with an image carrier 7 and an opposite electrode 8 is arranged on the other side of the image carrier 7. A photoconductor 12 and a resistor 13 are connected to an individual recording electrode 3 in parallel and DC power sources 14, 15 are respectively connected to the photoconductor 12 and the resistor 13. When a signal voltage is generated in the recording electrode 3 by impressing a voltage to the photoconductor 12 from the DC power source 14 and light is intermittently irradiated to the photoconductor 12 by using the DC power source 15 as an earth voltage, the magnetic toner 5 is transferred to the image carrier 7 by an electric field generated between the recording electrode 3 and the opposite electrode 8 and a toner image corresponding to the optical signal is formed.

摘要： PURPOSE:To permit recording to be performed without staining the back side of a recording medium by ink by avoiding the adherence of ink to the surface of a opposition electrode by providing an ink remover to remove ink adhered to the opposition electrode. CONSTITUTION:An ink remover 20 is provided on the opposite recorder side in relation to a rolled opposition electrode 8. In the ink remover 20, an ink absorber web 21 in contact with the surface of the electrode 8 along the longitudinal direction is attached to the plate 22 of a supporter. The plate 22 is slidably and detachably attached to the inside of the frame 24 of a holder. When ink reaches the remover 20 and comes into contact with the web 21 in a sliding manner as the electrode 8 turns, the ink is dissolved in the solvent, adsorbed, and removed. The staining with ink of the back of a new recording medium by ink adhere to the surface of the electrode 8 can thus be avoided, and good recording can be obtained.
