【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【産業上の利用分野】本発明は電子写真感光体、特に保護層を持つ電子写真感光体に関する。 The present invention relates to an electrophotographic photoreceptor, an electrophotographic photoreceptor, particularly with a protective layer.

【0002】 [0002]

【従来の技術】電子写真感光体には運用される電子写真プロセスに応じた所要の感度、電気特性及び光学特性を備えていることが要求されるが、更に、繰り返し使用される感光体にあっては、感光体の表面層、即ち支持体より最も離隔する層には、コロナ帯電、トナ−現像、紙への転写及びクリ−ニング処理等の電気的及び機械的外力が直接に加えられるために、それらに対する耐久性が要求されれる。 Required sensitivity of the Related Art Electrophotographic photosensitive members corresponding to the electrophotographic process to be operated, it is required that has an electrical and optical properties, further, there the photoreceptor is repeatedly used Te, the surface layer of the photosensitive member, i.e., the layer most apart from the support, corona charging, toner - development, transfer and chestnut to paper - for electrical and mechanical external force hardening treatment and the like can be added directly to the the durability against they are requested. 具体的には、摺擦による表面の摩耗やキズの発生、またコロナ帯電時に発生するオゾンによる表面の劣化等に対する耐久性が要求されている。 Specifically, the rubbing occurrence of wear and scratches of the surface by, also the durability is required for the deterioration of the surface due to ozone generated during corona charging. 一方、トナ−の現像及びクリ−ニングの繰り返しによる表面層へのトナ−付着という問題もあり、これに対しては表面層のクリ−ニング性を向上させることが求められている。 On the other hand, toner - also a problem that adhesion, chestnut surface layer contrary - - development and chestnut - toner to the surface layer by repetition of training to improve the training of being sought.

【0003】上記のような表面層に要求される特性を満たすために、樹脂を主成分とする表面保護層を設ける試みがなされている。 In order to satisfy the properties required for the surface layer as described above, it attempts to provide a surface protective layer mainly composed of resin have been made. 例えば特開昭57−30843号公報に提案されているように、導電性粉末として金属酸化物を添加して抵抗を制御した保護層が提案されている。 For example, as proposed in JP 57-30843 discloses a protective layer having a controlled by adding resistance metal oxide has been proposed as a conductive powder.

【0004】しかしながら、従来用いられていた方法では、金属酸化物微粒子の結着樹脂中での分散性、凝集性、保護層に用いた際の導電性、透明度に問題があり、 However, in the method which has been conventionally used, dispersibility in the binder resin in the metal oxide fine particles, cohesive, conductivity when used in the protective layer, there is a problem with transparency,
保護層表面の不均一性、ムラ等による画像欠陥、繰り返し帯電による残留電位の上昇、感度低下といった現象が起こりやすかった。 Non-uniformity of the protective layer surface, image defects due to unevenness, increase in residual potential due to repeated charging phenomena such sensitivity reduction was easy to occur.

【0005】また、透明度、導電均一性を保護層に付与するためには、超微粒子粉体(一次粒径0.1μm以下)を分散することが更に有用であるが、このような超微粒子粉体は通常の微粒子(一次粒径0.5μm以上) Further, transparency, conductivity uniformity in order to impart the protective layer is to distribute the ultrafine powder (hereinafter primary particle diameter 0.1 [mu] m) are further useful, such ultra-fine powder body ordinary fine particles (primary particle diameter 0.5μm or more)
以上に樹脂中への安定分散が困難であり、経時で二次凝集が進み分散粒径が増大し、透明度、導電均一性が低下していくという問題があり、このことは、特に高湿下において、繰り返し帯電により発生するオゾン、NO X等のコロナ生成物等が表面に付着することにより感光体の表面抵抗の低下を引き起こし、画像流れが発生する等の問題により、未だ保護層として満足できる電子写真特性を示すものは得られていない。 Above it is difficult to stably disperse into resin, dispersed particle diameter proceeds with time in the secondary aggregation increases, transparency, conductivity uniformity there is a problem that decreases, this is particularly high humidity under in causes a reduction in the surface resistance of the photosensitive member by ozone generated by repeatedly charging, corona products such as NO X or the like adheres to the surface, the problem that the image flow occurs, satisfactory as yet protective layer It shows the electrophotographic characteristics can not be obtained.

【0006】 [0006]

【発明が解決しようとする課題】本発明の目的は、繰り返し電子写真プロセスにおいて発生するコロナ生成物付着による表面抵抗の低下がなく、高湿下においても高品位の画質を保つことのできる電子写真感光体を提供すること、更に別の目的は、滑り性に優れ、摺擦による表面の摩耗やキズの発生等に対して耐久性を有する電子写真感光体を提供すること、更に別の目的は、繰り返し電子写真プロセスにおいて、残留電位の蓄積や感度の低下がない安定した電子写真特性を示す電子写真感光体を提供することである。 SUMMARY OF THE INVENTION It is an object of the present invention, no decrease in surface resistance due to the corona products adhering to occur in repetitive electrophotographic process, electrophotographic capable of maintaining image quality of high quality in high humidity providing a photosensitive member, still another object is excellent in sliding property, to provide an electrophotographic photoreceptor having a durability against generation of abrasion and scratches of the surface by rubbing, still another object in repeated electrophotographic process, is to provide an electrophotographic photosensitive member showing stable electrophotographic characteristics is not decreased accumulation and sensitivity of the residual potential.
