    • A photoconductor drum cleaning apparatus in an electrophotographic printer is disclosed which is simple in makeup, which allows a wiping roll to be rotated to follow rotation of the photoconductor drum is rotated and to be serviced for a prolonged life and is capable of performing an improved cleaning operation. To this end, the photoconductor drum 1 comprises: disposed in order from upstream in the direction of the photoconductor drum, a blade scraper 11 contacting with the surface of the rotating photoconductor drum and a wiping roll 12 rotating reversely in rubbing contact with the surface of the rotating photoconductor drum; disposed upstream of an area of rubbing contact of the rotating wiping roll with the photoconductor drum, a squeezing roll 13 rotating normally in pressure contact with the surface of the rotating wiping roll; and disposed downstream of an area of rubbing contact of the rotating wiping roll with the photoconductor drum and upstream of the rotating squeeze roll, a brush roll 14 rotating normally or reversely in pressure contact with the surface of the rotating wiping roll, the brush roll having a portion of its outer periphery immersed in a cleaning carrier solution.
    • 公开了一种电子照相打印机中的感光鼓清洁装置,其简单的化妆,其允许擦拭辊旋转以跟随感光鼓的旋转旋转并且被维持以延长使用寿命并且能够进行改进的清洁 操作。 为此,感光鼓1包括:从感光鼓的方向上游依次设置有与旋转的感光鼓的表面接触的刮刀11和与该表面相互摩擦接触的擦拭辊12, 旋转感光鼓; 设置在旋转的擦拭辊与感光鼓的摩擦接触区域的上游,与旋转的擦拭辊的表面压力接触的挤压辊13; 并且设置在旋转擦拭辊与感光鼓与旋转挤压辊的上游的摩擦接触区域的下游,与旋转擦拭辊的表面压力接触地正转或反向旋转的刷辊14,刷辊具有 其外周的一部分浸入清洁载体溶液中。
