Patent number: 6529700Abstract: The present invention provides a liquid carrier removing system which efficiently removes liquid carrier from a liquid developed image on a latent image bearing member, and reduces disturbance of a visible image formed with toner particles. The liquid carrier of the liquid developed image on the latent image bearing member is sucked by an absorbing cylinder, the surface of which is formed by a porous layer and pressed to the bearing member. A vacuum system is coupled to the absorbing cylinder to make the inside of the cylinder be negative pressure. The liquid carrier taken in the absorbing cylinder is sucked and collected inside the cylinder. In order that the pressed region of the absorbing cylinder may not be subjected to the sucking action by the negative pressure, a shield, which covers a part of the inside wall of the absorbing cylinder, is provided. Sucking and removing the liquid carrier of the liquid developed image and collection of the sucked liquid carrier are carried out separately.Type: GrantFiled: June 29, 2001Date of Patent: March 4, 2003Assignee: Kabushiki Kaisha ToshibaInventors: Hideki Nukada, Yasushi Shinjo, Yuko Nomura

Patent number: 5852453Abstract: An auxiliary substrate is provided so as to face a main substrate to which ink is supplied and the pattern of a voltage applied to an auxiliary electrode array formed on the auxiliary substrate is controlled. In a printing operation, the coloring material components are sent to the vicinity of an ink droplet emitting outlet and the coloring material components in the ink where the coloring material is dispersed in solvent are concentrated. Then, they are emitted from the ink droplet emitting outlet in the form of ink droplets and are forced to fly at a printing medium, thereby printing on the medium. In a non-printing operation, the auxiliary electrode array is controlled so that the coloring material components may be kept away from the ink droplet emitting outlet and the concentration of the coloring material components in the ink near the ink droplet emitting outlet is made lower than in a printing operation.Type: GrantFiled: March 4, 1996Date of Patent: December 22, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Shuzo Hirahara, Hitoshi Nagato, Yuko Nomura, Koichi Ishii, Yasuo Hosaka, Hideyuki Nakao, Teruo Murakami

Patent number: 5835113Abstract: An ink jet printing apparatus, in which the ink having colorants distributed in a solvent is supplied over the electrode array on the surface of the head substrate such that the electrode array is completely covered by the ink, while voltages are applied to the electrode array to produce an electric field for exerting an electrostatic force on the colorants in the ink such that the colorants are compressed and ejected toward a recording medium. Each individual electrode constituting the electrode array can have a tip end portion projecting from the surface of the head substrate. The apparatus also has an element for compressing colorants distributed in a solvent of an ink and an element for ejecting the compressed colorants toward a recording medium which are provided separately. In addition, the apparatus can incorporate an element for conveying colorants in the ink through the ink supply passage toward the colorant ejection point on the electrode array.Type: GrantFiled: September 22, 1995Date of Patent: November 10, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Shuzo Hirahara, Yasuo Hosaka, Hitoshi Nagato, Koichi Ishii, Yuko Nomura, Hideyuki Nakao, Teruo Murakami
