  • Electrostatic recording apparatus and image density control method thereof
    Patent number: 6509918
    Abstract: In an electrostatic recording apparatus, a recording medium is transported to a vaporized solvent supply unit where a vaporized organic solvent is given to the recording surface of the recording medium. Then, the recording medium is transported to an electrostatic recording head where an electrostatic latent image is formed on the recording medium. Next, the recording medium is transported to a development processing unit where the development process of the electrostatic latent image using a liquid toner is performed.
    Type: Grant
    Filed: December 19, 2000
    Date of Patent: January 21, 2003
    Assignee: Nippon Steel Corporation
    Inventors: Yoshinori Akichika, Toshiaki Ohira

  • Color electrostatic recorder with adjustable pressure on a recording medium
    Patent number: 6160564
    Abstract: A color electrostatic recorder of a single path system includes electrostatic recording heads conveyed in sliding contact with a recording medium for forming electrostatic latent images, developers provided in pairs to the electrostatic recording heads for developing the electrostatic latent images, and adjustable sliding contact of the recording medium with the electrostatic recording heads. The electrostatic recording heads and developer are provided in series as required, the radii of surface curvature in the electrostatic recording heads are made larger on the downstream side in the moving direction of a recording medium than on the upstream side, and the pressure of electrostatic recording heads on the recording medium is adjustable according to the type of the recording medium.
