    • An apparatus and a method for forming an image is provided that uses a contact type transfer member and a retract mechanism so as to transfer a toner image onto a continuous medium, performs the transfer process stably onto various continuous media and reduces unnecessary transfer of toner from the contact type transfer member to the continuous medium.The unnecessary transfer of toner may be caused by a concentration of contact stress when the contact type transfer member (16), which is moved by a retract mechanism, contacts with the continuous medium (25). To dissipate the contact stress, the transfer member (16) contacts with the continuous medium (25) while the continuous medium (25) is steadily conveyed and the transfer member is steadily rotated. Accordingly, the transfer of the toner from the transfer member (16) to the continuous medium (25) may be reduced. Furthermore, the friction at the contact line may be reduced and thus staining of the continuous medium may be further reduced.
    • 提供一种用于形成图像的装置和方法,其使用接触型转印构件和缩回机构,以将调色剂图像转印到连续介质上,将转印过程稳定地进行到各种连续介质上,并且减少不必要的调色剂转印 接触型转印构件连续介质。 当通过缩回机构移动的接触型转印构件(16)与连续介质(25)接触时,调色剂的不必要的转印可能由接触应力的集中引起。 为了消散接触应力,传递构件(16)与连续介质(25)接触,而连续介质(25)稳定地传送并且传送构件稳定地旋转。 因此,可以减少调色剂从转印部件(16)到连续介质(25)的转印。 此外,可以减少接触线处的摩擦,从而可以进一步降低连续介质的污染。

    • 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。
