    • There is disclosed a method for operating an electrophotographic copying apparatus having a latent image forming unit for forming an electrostatic latent image on a recording medium, a development unit for visualizing the electrostatic latent image with a developer containing toner and carrier to produce a visible toner image, and a fixing unit for fixing the toner image. In this operation method, the development unit is raced until the amount of charge on the toner in the developer reaches a predetermined level, and thereafter a usual electrophotographic copying procedure commences, whereby reduction in density of developed images during the initial operation of the electrophotographic copying apparatus can be prevented and developed images of high quality can be obtained.
    • 公开了一种用于操作具有用于在记录介质上形成静电潜像的潜像形成单元的电子照相复印设备的方法,用于使含有调色剂和载体的显影剂使静电潜像可视化的显影单元以产生可见的调色剂图像 以及用于固定调色剂图像的定影单元。 在该操作方法中,显影单元进行直到显影剂中的调色剂的电荷量达到预定水平,然后开始通常的电子照相复印过程,从而在电子照相复印的初始操作期间显影图像的浓度降低 可以防止装置,并且可以获得高质量的图像。
