摘要： At least a photosensitive drum 2 and charge roller 9 are attached to a unit 8 so that the photosensitive drum 2 and charge roller 9 can be freely attached to and detached from an apparatus body 1 in unison with the unit case 8, and the charge roller 9 can be freely brought into and out of contact with the surface of the photosensitive drum 2. The apparatus body 1 is provided with pressure cams 5a and 5b adapted to cause the charge roller 9 to be brought into and out of contact with the surface of the photosensitive drum 2.

摘要： In an image forming apparatus, a charging member, image transfer member or similar contact member contacts an image carrier implemented as a photoconductive element. Even when a voltage is applied to the contact member in a relatively low temperature environment, the contact member is provided with an adequate charge potential or an image transfer potential.
摘要翻译：在图像形成装置中，充电构件，图像转印构件或类似的接触构件接触实现为光导元件的图像载体。即使当在较低温度的环境中对接触构件施加电压时，接触构件也被提供足够的充电电位或图像转移电位。

摘要： A device for cleaning a wire of a corona discharge type charger installed in an electrophotographic copier or similar image recording apparatus such as a charger for charging a photoconductive element, a transfer charger or a separation charger. The device includes a pair of cleaning pads which clean the wire by individually holding diametrically opposite portions of the periphery of the wire, i.e. a portion which faces the surface of the photoconductive element to be charged and a portion which is remote from the surface of the same element. The cleaning pads act on the wire only when the pads and the wire are moved in one predetermined direction relative to each other.
摘要翻译：一种用于清洁安装在电子照相复印机或类似图像记录装置中的电晕放电型充电器的线的装置，例如用于对感光元件充电的充电器，转印充电器或分离充电器。该装置包括一对清洁垫，其通过单独地保持线的周边的径向相对的部分，即面向待充电的光电导元件的表面的部分和远离该电极的表面的部分来清洁电线相同的元素只有当垫和线相对于彼此沿一个预定方向移动时，清洁垫才能作用在线上。
