ドラム素管の洗浄方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for cleaning a drum tube used as a conductive substrate of a photoreceptor in manufacturing a photoreceptor used in an electrophotographic copying machine or the like.
（従来の技術）
電子写真複写機等に用いられる感光体は、通常導電性基
体であるドラム素管の表面に塗工液を塗布・乾燥して製
造されている。(Prior Art) Photoreceptors used in electrophotographic copying machines and the like are usually manufactured by applying a coating liquid to the surface of a drum tube, which is a conductive substrate, and drying the coating liquid.
感光体を製造するにあたって、ドラム素管の表面に油分

後、ドラム素管を塗工液塗布工程へ送るようにしている
。When manufacturing photoreceptors, if foreign matter such as oil (human fat or cutting oil) adheres to the surface of the drum tube, it will cause image unevenness and greatly reduce the photosensitive characteristics. In the cleaning step, the drum tube is washed with a solvent or the like to completely remove oil and other stains adhering to the surface of the drum tube, and then the drum tube is sent to the coating liquid application step.
従来、ドラム素管を洗浄するには、洗浄液が入れられた
タンクの上方にドラム素管を配設し、このドラム素管を

いた。Conventionally, in order to clean a drum tube, the drum tube is placed above a tank containing cleaning liquid, and the drum tube is immersed in the direction of the cleaning wave while rotating in the circumferential direction, and then pulled out from the cleaning liquid. This was done repeatedly and by sliding a brush placed in the tank around the drum tube.

の点で満足するに至っていないのが実状である。By the way, CFCs are usually used as conventional cleaning liquids, and when CFCs are used, it is possible to degrease the drum tube relatively well, but it also prevents the deterioration of brushes made of animal hair, for example. do not have. However, in recent years, the use of fluorocarbons has become a social problem because it causes environmental pollution, and there is a possibility that it may become unusable in the future. It is also possible to use other organic solvents other than Freon, such as aromatic solvents and alcohol solvents, but these solvents are not yet satisfactory in terms of cleaning power, explosion risk, etc. This is the actual situation.
