    • A latent electrostatic image developing device for developing a latent electrostatic image formed on an image-bearing member by applying a developer thereto. The developing device comprises a developer applicator means for holding the developer on its surface, carrying the developer to a developing zone and applying it to the latent electrostatic image in the developing zone and a bias voltage applying means for applying a bias voltage to the developer held on the surface of the developer applicator means. The developing device further includes a detector means for detecting the relative humidity of the environmental atmosphere and a control means for changing the magnitude of the applied bias voltage to a lower value when the detected relative humidity of the atmosphere exceeds a predetermined value.
    • 一种静电潜像显影装置,用于通过将显影剂施加到图像承载部件上来形成静电潜像。 显影装置包括用于将显影剂保持在其表面上的显影剂施加装置,将显影剂携带到显影区域并将其施加到显影区域中的静电潜像;以及偏置电压施加装置,用于向显影剂施加偏置电压 在显影剂施加装置的表面上。 显影装置还包括用于检测环境气氛的相对湿度的检测器装置和当所检测的大气相对湿度超过预定值时将所施加的偏置电压的大小改变为较低值的控制装置。

    • An electrostatic photographic copying machine includes a photosensitive body having a photosensitive layer on its surface, a charging apparatus, a developing device and a transfer device arranged along a moving passage of the photosensitive body. An optical system projects an image of an original onto the surface of the charged photosensitive body, and a fixation apparatus fixes a transferred image onto copying paper. The electrostatic photographic copying machine is provided with an original paper inserting port, an original paper carrying passage, a first original paper discharging port for discharging the original paper in a forward direction, a second original paper discharging port for discharging the original paper in a rearward direction, a copying paper supplying apparatus, copying paper carrying passages, a first copying paper discharging port for discharging the copying paper in a forward direction, a second copying paper discharging port for discharging the copying paper in a rearward direction, and changing mechanism for changing the directions of movement of the original paper and the copying paper to the forward and rearward directions thereof, respectively.
    • 静电复印机包括其表面上具有感光层的感光体,充电装置,显影装置和沿着感光体的移动通道布置的转印装置。 光学系统将原稿的图像投影到带电感光体的表面上,并且固定装置将转印的图像固定在复印纸上。 静电复印机设置有原纸插入口,原纸输送通道,用于向前方排出原稿的第一原纸排出口,用于将原纸向后排出的第二原纸排出口 方向,复印纸供给装置,复印纸携带通道,用于向前方排出复印纸的第一复印纸排出口,向后方排出复印纸的第二复印纸排出口,以及用于改变 原纸和复印纸分别向前后方向移动的方向。
