  • Publication number: 20120038970
    Abstract: The present invention provides a method of manufacturing a display medium, including: preparing a first substrate on which a gap retaining member that retains a gap between substrates is disposed in a protruded form; applying an adhesive to a top surface of the gap retaining member; disposing a particle dispersion liquid on an area surrounded by the first substrate and the gap retaining member; and adhering the first substrate and a second substrate together via the gap retaining member, by contacting the second substrate with the adhesive applied to the top surface of the gap retaining member and drying the solvent of the adhesive so as to adhere the second substrate to the top surface of the gap retaining member by the adhesive component of the adhesive.

  • Publication number: 20110020037
    Abstract: A developing device includes a first developer containing chamber, a second developer containing chamber, a first inflow section, a second inflow section, a first conveyance member and a second conveyance member. The first inflow section allows the developer to flow from the second developer containing chamber into the first developer containing chamber. The second inflow section allows the developer to flow from the first developer containing chamber into the second developer containing chamber. The first conveyance member conveys the developer contained in the first developer containing chamber in a first developer conveyance direction. The second conveyance member conveys the developer contained in the second developer containing chamber in a second developer conveyance direction.

  • Patent number: 7509080
    Abstract: A developing unit which includes a conveying shaft; a developing conveying portion conveying a developer in an axial direction as the conveying shaft rotates; a discharge opening discharging the developer from the inner wall surface; an accumulating chamber accumulating the discharged developer; and an opening/closing member opening and closing the discharge opening due to its own weight as the rotating body rotates, and being in an open state at the developing position, an opening/closing fulcrum of the opening/closing member being at a lower end portion of the opening/closing member at the developing position, the developing unit being held at a rotating body, and successively being made to oppose a developing position of an image carrier due to rotation of the rotating body.
