    • A charging method for charging a photosensitive material of, for example, the photosensitive drum of an electrophotographic copying apparatus is accomplished by bringing an endless electrically conducting flexible sheet containing a brush roller into physical contact with the surface of the photosensitive material and applying a voltage to the electrically conducting flexible sheet. The electrically conducting flexible sheet is a laminate of a first resistance layer positioned on the side of the brush roller and a second resistance layer positioned on the outer surface of the first resistance layer. The second resistance layer has an electric resistance greater than that of the first resistance layer. The method using the laminated flexible sheet makes it possible to uniformly and stably charge the surface of the photosensitive material without the life of the photosensitive material being deteriorated and without permitting the output of the power source to drop even when defects, such as pinholes, exist in the surface of the photosensitive material.
    • 用于对例如电子照相复印设备的感光鼓的感光材料充电的充电方法是通过使含有刷辊的环形导电柔性片材与感光材料的表面物理接触并将电压施加到 导电柔性片。 导电柔性片是位于刷辊一侧的第一电阻层和位于第一电阻层的外表面上的第二电阻层的叠层。 第二电阻层的电阻大于第一电阻层的电阻。 使用层叠的柔性片的方法使得可以均匀且稳定地对感光材料的表面充电,而不会使感光材料的寿命恶化,并且即使存在诸如针孔的缺陷,也不允许电源的输出下降 在感光材料的表面。
