    • Provided is a projection type liquid crystal display apparatus, which can improve black-level display and thus can display a higher-contrast image as compared to the related art. An optical compensator is located on the light exit side with respect to the liquid crystal display device so as to compensate for the optical phase difference caused by liquid crystal molecules in a light-entry-side region of the liquid crystal layer. As the optical compensator is located on the light exit side with respect to the liquid crystal display device, birefringence, caused by the liquid crystal molecules present in the light-entry-side region, is compensated for without being influenced by a microlenses provided in the liquid crystal plane. Consequently, the apparatus can improve the black-level display and thus can display a higher-contrast image as compared to the related art. Further, a phase difference caused by the birefringence of the nematic liquid crystal molecule is compensated for by using a substance having properties optically opposite to the positive crystal, namely, a substance having birefringence equivalent to birefringence of a negative crystal.
    • 提供一种投影型液晶显示装置,与现有技术相比,可以改善黑色级显示,因此可以显示较高对比度的图像。 光补偿器相对于液晶显示装置位于光出射侧,以补偿由液晶层的光入射区域中的液晶分子引起的光学相位差。 由于光学补偿器相对于液晶显示装置位于光出射侧,因此存在于入射侧区域中的液晶分子引起的双折射被补偿,而不受设置在光入射侧区域中的微透镜的影响 液晶平面。 因此,与现有技术相比,该装置可以改善黑电平显示,因此可以显示较高对比度的图像。 此外,通过使用具有与正晶相反的光学相反特性的物质,即具有与负晶体的双折射相当的双折射的物质来补偿由向列型液晶分子的双折射引起的相位差。

    • An electrostatic latent image formed on a photosensitive drum is electrostatically developed with a non-magnetic type developer, and is electrostatically transferred from the drum to a paper. The developer is composed of a toner component and a resin powder component, one component of which has a polarity opposite to that of an electric charge of the other component generated by triboelectrification therebetween. In the developing process, a conductive foam rubber developing roller is used, which includes a conductive tubular foam rubber roller element, and a metal shaft inserted into a central bore thereof. The roller element has an outer thicker portion including a conductive filler dispersed therein, and an inner solid skin layer defining the central bore thereof and exhibiting an electrical resistivity considerably higher than that of the thicker portion for lack of conductive filler. Nevertheless, a sufficient electrical contact is established between the roller element and the shaft. A thin metal blade is pressed against the roller for regulating the thickness of the developer entrained thereby, and is arranged to compensate for a resilient deformation of the shaft caused when pressing the blade against the roller.
