い。それゆえ、最近の複写機、特に、低速機には。(Prior Art) In order to obtain clear electrophotography, an electrophotographic photoreceptor must be uniformly charged. For this purpose, it is essential that the photosensitive layer be formed on the surface of the conductive substrate to have a smooth and uniform thickness. Various inorganic and organic photosensitive materials are known for forming photosensitive layers. Inorganic photosensitive materials have hard surfaces and are highly durable, so they are suitable for large, high-speed machines, but they are expensive and often harmful to the human body. Therefore, modern copiers, especially low-speed ones.

されている。Poly-N-vinylcarbazole is generally used as an organic photosensitive material. However, since poly-N-vinylcarbazole is inflexible and brittle, the abrasion resistance of the formed photosensitive layer is low. In order to improve wear resistance, it has been proposed to include a reinforcing agent such as vinylidene chloride-acrylonitrile copolymer or polycarbonate resin.

た。In addition to containing reinforcing agents with excellent hardness such as polycarbonate resin and flexible rubber-like reinforcing agents such as vinylidene chloride-acrylonitrile copolymer, stearin is also added to reduce the coefficient of friction of the organic photosensitive layer. The invention was completed based on the inventor's knowledge that by adding an acid metal (lubricant), the lubricating effect of metal stearate is added, and an organic photoreceptor with excellent wear resistance can be obtained.

的が達成される。The electrophotographic organic photoreceptor of the present invention is an electrophotographic organic photoreceptor containing poly-N-vinylcarbazole as a charge transport medium and a reinforcing agent, and further contains metal stearate as a reinforcing agent. Thus, the above objective is achieved.

する。Examples of metal stearates include zinc stearate, aluminum stearate, and sodium stearate. The metal stearate is contained in an amount of 0.1 to 15 parts by weight, preferably 1 to 6 parts by weight, based on 100 parts by weight of poly-N-vinylcarbazole. More preferably, the amount is 3 parts by weight. If it is less than 0.1 part by weight, the photosensitive layer of the organic photoreceptor obtained in 5 will not have sufficient abrasion resistance. 15
When the amount exceeds 1 part by weight, the sensitivity of the obtained organic photoreceptor decreases.

Significant improvement in wear resistance. The reinforcing agent is preferably contained in an amount of 5 to 20 parts by weight per 100 parts by weight of poly-N-vinylcarbazole.If it is less than 5 parts by weight, the resulting photosensitive layer will have satisfactory abrasion resistance. It has no gender.

その結果を第１図に示す。The surface hardness of the photosensitive layer of this photoreceptor is JI3 pencil hardness 2H
Met. This photoreceptor was evaluated in the same manner as in Example 1,
The results are shown in FIG.
実施例および比較例から明らかなように１本発明の感光
体は、従来の感光体に比べて、長期間にわたる使用によ
っても膜厚の削れ度合が少ない。As is clear from the Examples and Comparative Examples, the photoreceptor of the present invention shows less wear in film thickness than conventional photoreceptors even after long-term use.
これは本発明の感光体が耐摩耗性および表面硬度に優れ
ていることを示している。This shows that the photoreceptor of the present invention has excellent wear resistance and surface hardness.
（発明の効果） 本発明の電子写真用有機感光体は、このように。(Effect of the invention) The organic photoreceptor for electrophotography of the present invention is thus prepared.
補強助剤としてステアリン酸金属を含有するため。Because it contains metal stearate as a reinforcing aid.
ステアリン酸金属の潤滑効果により基体と有機感光層と
の摩擦係数が小さくなり、そのために耐摩耗性が向上す
る。その結果、複写過程のブレードクリーニング工程に
おける感光層の摩耗や転写工程における祇づまりなどに
よる感光層表面の擦過傷の発生が防止され得るため、鮮
明な電子写真複写画像が得られる。The lubricating effect of metal stearate reduces the coefficient of friction between the substrate and the organic photosensitive layer, thereby improving wear resistance. As a result, scratches on the surface of the photosensitive layer due to abrasion of the photosensitive layer during the blade cleaning step of the copying process and clogging during the transfer process can be prevented, so that clear electrophotographic copied images can be obtained.
