【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、電子写真感光体に用いられる梱包材に関す

ている。Generally, electrophotographic photoconductors are very susceptible to scratches.For example, when the photoconductors are used in a curling type electrophotographic copying machine, dents, scratches, fingerprints, oil stains, and solvents formed on the photoconductor surface. The effects of acid, alkali, and exposure to ultraviolet rays have various adverse effects on the image. Therefore, in order to prevent such damage during handling, the packaging form of the photoconductor surface has been conventionally provided with a protective mechanism, or in the case of amorphous selenium (a-Se), etc. Has a form that does not touch anything.
一方、従来において感光体の交換作業は専門の作業者

提案されてきた。On the other hand, in the past, the replacement of the photoconductor was performed by a specialized worker (service person), but in recent years, with the spread of the electrophotographic apparatus, general users can also replace the photoconductor of the electrophotographic copying apparatus. There is an increasing demand for easy work. In order to solve such problems, various methods using a protective cover on the photoconductor have been proposed in recent years.

いう欠点も出てきた。However, the various conventional methods have a drawback in that the protective cover and the surface of the electrophotographic photosensitive member are rubbed with each other to cause abnormal images such as stripes, black spots, white spots, and unevenness. In the case of using a photocopier, there is also a drawback that the blade is turned over and cleaning failure occurs because there is no lubricant such as toner on the surface of the photoconductor.

As shown in the figure, the electrophotographic photosensitive member 10 is packed by a packing material 2 with a lubricant in contact with the surface to which the lubricant is attached. Further, when the packing material 2 with lubricant is removed and attached to the copying machine body (not shown) of the electrophotographic photoreceptor 10, the solid lubricant 6 of the packing material 2 with lubricant is provided on the surface of the electrophotographic photoreceptor 10. Blades (not shown) for subsequent use due to
Can be prevented from reversing. The electrophotographic photoreceptor 10
During use, the powdery solid lubricant 6 selected from silicone-based, molybdenum-based, and fluorine-based is gradually scraped off by a blade or the like, so the lubricating effect of the solid lubricant decreases, but conversely the toner Since it gradually adheres to the blade and the photoconductor, the lubrication effect of the toner increases,
Since the toner gradually roughens the surface of the photoconductor, the friction between the photoconductor and the blade is reduced, and the reversal of the blade is continuously prevented.
