Further, according to the above-mentioned coating method, coating liquid clumps may occur on the end portion and back surface (or inside) of the photoreceptor, which may impede the above-mentioned insertion. Furthermore, since the ends of the electrophotographic photoreceptor are subjected to conductive treatment, if an organic layer is present at these ends, the conductive treatment is not carried out effectively.

特開昭６０−１７０８５８号公報に記載される方法では
、電子写真感光体の必要な塗膜表面に有機溶剤が飛散し
、有機溶剤蒸気がたちこめるため。(Problems to be Solved by the Invention) In the method described in JP-A-60-170858, the organic solvent scatters on the surface of the necessary coating film of the electrophotographic photoreceptor, and organic solvent vapor builds up.

できないことがある。The method described in JP-A No. 60-119562 has the same drawbacks as above, and furthermore, since a rubber blade is used, it is necessary to use a chlorinated solvent, a strong alkaline solvent, or a solvent with strong dissolving power. Scraping off is often difficult, and when such solvents are used, the above-mentioned disadvantages are exacerbated. In addition, problems such as polishing and adhesion of polishing powder occur, and the photoconductive layer is easily damaged near the boundary line where the photoconductive layer is removed. In this case, when the ultrasonic wave is applied to the substrate, the surface of the solvent becomes violently rippled, which causes the solvent to scatter, and further increases the mist and evaporation of the solvent. As a result, disturbance of the removal boundary line, uneven thickness of the necessary photosensitive layer or resin layer, etc. are likely to occur. Further, if the photosensitive layer or resin layer is dried and hardened, it may not be possible to peel off the photosensitive layer or resin layer by applying ultrasonic waves.

Second, it provides a method for manufacturing an electrophotographic photoreceptor without disturbing the removal boundary line. Third, it provides an electrophotographic method that enables removal of coating liquid spots. A method for manufacturing a photoreceptor is provided.

透を防ぐために好ましい。In the method according to the present invention, the end portion of the organic layer of the electrophotographic photoreceptor as shown in FIG. 1 or FIG. A shielding material is provided along the boundary between the area and the non-removed area. The shielding material may be in contact with the electrophotographic photoreceptor or may have a gap, but in this case, the portion of the shielding material that contacts the electrophotographic photoreceptor or the closest portion (hereinafter referred to as the tip) is a wire. In order to prevent the removal liquid from permeating into the part where the organic layer is not removed, it is preferable to configure the removal liquid to have a shape or a surface with a slight width (preferably a surface with a width of one width or less).

要となるため電子写真感光体の量産には不適当となる。As the shielding material, backings such as 0-rings, ■-rings, flat rings (wide ones), sealing materials, etc. may be used as the tip portion of the shielding material. At this time, the shielding material and the electrophotographic photoreceptor may not be brought into contact with each other, or may be brought into contact with each other. In the former case, 0-ring, ■-ring,
Since the tips of flat rings and the like are planar or planar rather than linear, the removal liquid easily penetrates into the gap between them and the photoreceptor, and the boundary line between the removed area and the non-removed area becomes unclear. Easy to use. In the latter case, if the backing, sealing material, etc. of the 0-ring, ■-ring, flat ring, etc. are tightened to bring them into close contact with the electrophotographic photoreceptor, the boundary line will not only become unclear as described above, but also the organic matter near the boundary line will be Increase in layer thickness, uneven removal of the organic layer near the boundary line and peeling of unremoved areas due to this, peeling of the organic layer when releasing tightening, and staining of the seal itself are likely to occur. When the material is used repeatedly, it is necessary to clean the seal dirt and tighten and release the shielding material, making it unsuitable for mass production of electrophotographic photoreceptors.

Although the drawbacks are eliminated, there are still the same drawbacks as above, and also when installing the electrophotographic photoreceptor.
感光体端部の激突によシパッキング、シール材等を破壊
しやすく、引抜きに際し、導電性支持体に折、き傷が付

There is a one-touch coupler that allows easy replacement of backing, sealing material, etc., but this also covers the ends of the organic layer and is unusable.

まれる密閉構造とすることもできる。Note that the structure of the hood is designed so that it does not come into contact with the non-removed portion of the organic layer of the electrophotographic photoreceptor. Also,
If the shielding material comes into contact with the electrophotographic photoreceptor and the hood covers the entire electrophotographic photoreceptor, the upper end of the electrophotographic photoreceptor and the hood can be closed using a gasket or the like. It can also be a closed structure surrounded by a body, a hood and shielding material.

なうことができる。In addition, as a method of depressurizing or suctioning the removal part side,
This can be done by making the electrophotographic photoreceptor into a sealed structure so that it comes into contact with a shielding material in order to remove the end of the organic layer, connecting this to a pressure removal or suction device, and driving the pressure removal or suction device. .
電子写真感光体と遮蔽材の間に２間隙があっても差支え
ない。There may be no problem even if there are two gaps between the electrophotographic photoreceptor and the shielding material.
非除去部側の遮蔽材付近に気体を吹きつけても一部除去
部側に吹き込まれてもよい。The gas may be blown near the shielding material on the non-removed portion side, or may be partially blown toward the removed portion side.
