感光体の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing an endless belt photoreceptor, and more specifically to an endless belt in which a meandering prevention guide can be easily provided without adversely affecting the characteristics of the photoreceptor. The present invention relates to a method for manufacturing a belt photoreceptor.

スベルト感光体の蛇行を防止するために、感光体裏面端
縁に沿ってガイドを設ける技術は、既に知られている。Conventionally, a technique is already known in which a guide is provided along the back edge of the photoreceptor in order to prevent an endless belt photoreceptor from meandering when passed between a driving roller and a driven roller.

る。A method for manufacturing such a guide is disclosed in Japanese Patent Application Laid-Open No. 57-2141.
No. 67 discloses a technique for adhering a guide made of a neoprene rubber sheet or the like to the back surface of a photoreceptor using an adhesive, and JP-A-59-2309.5L discloses a technique for adhering a guide made of a neoprene rubber sheet or the like to the back surface of a photoreceptor, and Japanese Patent Application Laid-open No. 59-2309.5L discloses a guide made of a neoprene rubber sheet or the like made of elastic plastic. A technique is disclosed in which a guide is bonded by heating and melting a hot-melt binder resin, and Japanese Patent Application Laid-Open No. 59-230950 discloses a technique in which a hot-melt binder resin itself is used as a guide.

When a solvent is used, there is a problem that the photosensitive layer may dissolve due to the solvent.

As described in Publication No. 1, in the case of a hot melt (a type that exhibits an adhesive effect when heat is applied), heat may be applied to the photoreceptor. Further, in order to improve adhesion, it is necessary to preheat the photoreceptor. However, when the photoreceptor is heated, there are problems in that the photosensitive layer is thermally degraded, resulting in decreased sensitivity and the so-called crabking phenomenon in which the photosensitive layer cracks during repeated use.

ずる、接合部のちり上りがないという効果がある。The adhesive tape 8 is applied along both ends of the back surface of the insulating substrate, preferably within 5'ms of the tape end from one end. The width of the adhesive tape 8 is arbitrary, but a width of several widths is sufficient. Further, the thickness of the adhesive tape 8 may be set to such a degree that it can function as a guide, and may be appropriately determined within the range of 0.5 to 5 am. The adhesive tape 8 does not necessarily need to be attached to the entire circumference of the back surface of the insulating substrate, and a gap may be provided. Providing this gap means that the adhesive tape 8
This has the effect of making the bonding work easier and eliminating the dust build-up at the joint that occurs when no gap is provided.
