摘要： A roller is rotatable so that its surface moves in a direction opposite to a photoconductive drum to remove excess liquid developer from the drum. Rolling contact bearings are mounted on opposite ends of a shaft supporting the roller and have a diameter which is slightly larger than that of the roller so that when the bearings are pressed against the drum a slight clearance is maintained between the surfaces of the drum and the roller. The bearings are sealed and filled with a lubricant which does not degrade the liquid developer if mixed therewith. A wiper contacts the roller to remove developer pricked up thereby from the drum. Wipers are further disposed in contact with the drum upstream of the bearings to remove developer from the drum in these areas prior to contact with the bearings.
摘要翻译：辊可旋转，使得其表面沿与感光鼓相反的方向移动，以从鼓中去除多余的液体显影剂。滚动接触轴承安装在支撑辊的轴的相对端上，其直径略大于辊的直径，使得当轴承被压靠在滚筒上时，辊和滚筒的表面之间保持微小的间隙滚筒。轴承密封并填充润滑剂，如果与其混合，则不会使液体显影剂降解。擦拭器接触辊子以从鼓上除去由此引起的显影剂。在与轴承接触之前，擦拭器还进一步布置成与滚筒上游轴承接触，以将这些区域中的显影剂从滚筒中移出。

摘要： A roller is disposed parallel and adjacent to a photoconductive drum with a small gap inbetween. The roller is made of an electrically conductive material and covered with an insulating coating of hard anodized aluminum. The roller is fixed to a shaft which is driven to rotate the roller in the same direction as the drum to remove excess developing liquid from the drum through viscous friction. Electrically conductive bearings are mounted on the ends of the shaft which have an outer diameter greater than the diameter of the roller. The bearings rotatably contact the surface of the drum to maintain the gap. Either insulating plastic bushings or layers of alumite are disposed between the ends of the shaft and the bearings to insulate the shaft from the bearings and thereby from the drum.
摘要翻译：平行并相邻于感光鼓的辊子之间具有小的间隙。辊由导电材料制成，并被硬质阳极氧化铝的绝缘涂层覆盖。辊被固定到轴上，该轴被驱动以沿与滚筒相同的方向旋转辊，以通过粘性摩擦从滚筒除去多余的显影液。导电轴承安装在轴的端部，其外径大于辊的直径。轴承可旋转地接触滚筒的表面以保持间隙。绝缘塑料衬套或耐酸铝层设置在轴的两端和轴承之间，以将轴与轴承隔离，从而与滚筒隔离。
