レスベルト状感光体の製造方法に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photoconductor in an apparatus such as a copying machine, a printer, a facsimile or the like using an electrophotographic system, and more particularly to a method of manufacturing an endless belt-shaped photoconductor.

フィルムの両端部を数mm巾で接合していた。Conventionally, this type of endless belt-type photoreceptor has a conductive layer formed on a film such as PET, and spray coating, spinner coating, wire bar coating, blade coating, flow coating, etc. The photosensitive layers were sequentially laminated, and both ends of the laminated film were joined with a width of several mm.

た。In the conventional endless belt type photoreceptor described above, the photosensitive layer is formed by spray coating, blade coating,
After lamination by the flow coating method etc., the both ends of this laminated film are joined by bonding etc., and the joining part becomes a projection shape. When actually printing with an electrophotographic apparatus, the joined part is detected and electrophotography is performed. It is necessary to skip processes such as charging, exposure, development, and erasing of the system as necessary, and the device becomes complicated due to a detector at the joint, a skip mechanism, and the like. Had the disadvantage of doing so.

難しいという欠点があった。In addition, if a photosensitive layer is to be formed on a non-joined endless belt-like substrate which has been formed into a tubular shape in advance, it is different from coating on a flat surface, but uniform by spray coating, blade coating, and flow coating. It was difficult to form a film with a film thickness. In addition, when the film is formed by dip coating, if the coating is performed in a circular shape, if a large number of pieces are to be coated at one time, a wasteful space between the respective substrates increases, so mass production is performed. There was a drawback that it was difficult to do.
本発明の目的は前記課題を解決したエンドレスベルト

A method of manufacturing a photoreceptor, wherein the fixing jig has a pair of semicircular portions separated from each other by a spring and pressed in opposite directions, and the pair of semicircular portions formed by compressing the spring. The endless belt-shaped base is suspended around the outer periphery of the base, and the endless belt-shaped base is pushed and expanded along the outer circumference of a pair of semicircular portions by the spring force of a spring to deform and hold the base in an elliptical shape. The endless belt-like substrate deformed and held in a shape is immersed in a coating solution to form a coating film.
