    摘要: A screen printer effects a printing by moving a squeegee in contact with a screen to force a printing paste through a printing pattern formed on the screen. The squeegee is held by a squeegee head. The squeegee head includes a support member for supporting the squeegee in such a manner as to move the squeegee upward and downward, and at least one moving member which swingably supports the support member and is movable together with the support member. When the squeegee is to be exchanged, only the support member is angularly movable relative to the moving member so as to provide a sufficient space above the screen to facilitate the exchange of the squeegee.

    摘要: A large number of holes are formed in a two-layered porous film sandwiched between a lower substrate and an upper substrate and filled with a light transmitting liquid and fine particles. When a voltage is applied between an upper electrode and a lower electrode, migration of the fine particles, takes place based on electrophoresis. White color is displayed when the fine particles are located on an upper transparent porous film side and black color is displayed when the fine particles are located on a lower black porous film side. Color display is also possible by periodically repeating three primary colors of RGB in the lower layer porous film or arranging a color filter on the transparent upper substrate. Bubbles-containing fine particles or bubbles themselves may be employed in place of the fine particles.

    摘要: An object of the present invention is to prevent an electrical breakdown of a toner layer and an occurrence of overcurrent, thereby preventing quality of image from being degraded at the time of development, when development with one-component toner is conducted using a developing roller of low resistance. The resistance value Rd of a developing roller which carries and conveys one-component toner in a manner of coming into contact with a photoconductor which bears an electrostatic latent image, is defined as Rd=.rho.d.multidot.(Dd1/S1), wherein S1 (cm.sup.2) is an area in which the developing roller comes into contact with the static image bearing member via a toner layer, Dd1 (cm) is a layer thickness of a semiconductive layer which composes the developing roller, and .rho.d (.OMEGA..multidot.cm) is a volume resistivity thereof. The range of the resistance Rd is set as 10.sup.4 5.times.10.sup.7. By using the developing roller of low resistance, excellent development is realized and an electrical breakdown and an overcurrent can be avoided by the resistance value of the toner layer.

    摘要: A developing device has a development roller for carrying toner on a surface thereof, a toner supply roller for supplying the toner to the development roller, a flat spring which comes into contact with the development roller, charges the toner to be supplied to the development roller and applies the toner to the development roller while regulating the thickness of a layer of the toner. The flat spring has a plurality of flat-plate parts including a contact flat-plate part which comes into contact with the development roller, and a curved part which connects the flat-plate parts to each other. In this structure, by arbitrarily selecting dimensional parameters of the flat spring, it is possible to easily obtain various flat springs having different properties. Therefore, for example, the stress to the toner and the stress to the members can be easily reduced simultaneously with a design of the flat spring. Moreover, it is possible to improve the uniformity of the toner layer thickness in the axis direction of the development roller and the uniformity of charging of the toner.

    摘要: A developing device and a blade of the developing device, includes a contact section which is in plane contact with a development roller, and an inclined section which extends from an end of the contact section so as to form a flare at an inflow section of a one-component developer between the blade and development roller. When a flare angle between the blade having the flare and a line tangent to the development roller is denoted by a tilt angle &thgr;, 30°≦&thgr;≦90°. Thus, if the flare angle at the inflow section of the one-component developer between the blade and development roller is optimized, even when the one-component developer deteriorates with time, for example, the flowability is changed with time, it is possible to provide a developing device and a blade of the developing device capable of forming a one-component developer layer with an extremely stable deposit of one-component developer. Moreover, it is possible to provide a blade which can increase the dimensional tolerance of the inclined section and can be produced easily at a low cost.
