    • An image forming apparatus is provided with a movable image bearing member, such as a movable amorphous silicon photosensitive member, and an image forming member forms an image on a surface of the image bearing member. The image on the surface of the photosensitive member is transferred to a transfer material. A separator electrostatically separates the transfer material from the photosensitive member after the image is transferred by the transferring member. The separator is supplied with an electric power having a voltage of a waveform which periodically changes. In one embodiment, the voltage waveform includes at least two sine waves of different frequencies superposed to lower the peak value of the first sine wave.

    • For a liquid crystal display apparatus, an orientating film of an electrode substrate including more signal electrodes than scanning electrodes in a predetermined range receives a uniaxial orientation treatment parallelly or almost parallelly to a lengthwise direction of the signal electrodes. Besides, an orientating film of an electrode substrate including the scanning electrodes receives a uniaxial orientation treatment perpendicularly or almost perpendicularly to a lengthwise direction of the scanning electrodes. The electrode substrates are combined so that the directions of the uniaxial orientation treatment of the orientation films become parallel to each other. This enables growth of a smectic layer to be less frequently hindered by differences in level caused by the electrodes. Thus a uniform C2U orientation can be obtained easily. Consequently, the liquid crystal display apparatus realizes a uniform orientational state with no defects and uniform and high-contrast display properties.
    • 对于液晶显示装置,包括比预定范围内的扫描电极多的信号电极的电极基板的取向膜接收与信号电极的长度方向平行或几乎平行的单轴取向处理。 此外,包括扫描电极的电极基板的取向膜与扫描电极的长度方向垂直或几乎垂直地接收单轴取向处理。 电极基板的组合使得取向膜的单轴取向处理的方向相互平行。 这使得近晶层的生长不会被电极引起的水平差异所阻碍。 因此可以容易地获得均匀的C2U取向。 因此,液晶显示装置实现均匀的取向状态,没有缺陷和均匀的高对比度显示特性。
