Description

【0001】
【発明の属する技術分野】
本発明は電子写真感光体に関し、詳しくは特定の電荷輸送材料を組み合わせて使用した、高感度であり、且つ多数回繰り返し使用における静電特性、画像特性などが良好な繰り返し安定性に優れた電子写真感光体に関する。
【0002】
【従来の技術】
有機系の電子写真感光体において、その感度を高めるために電荷発生材料と電荷輸送材料を含有する感光層を有する機能分離型の電子写真感光体、特に、電荷発生材料を含有する電荷発生層と電荷輸送材料を含有する電荷輸送層とを積層した機能分離型の電子写真感光体が注目され実用化されている。この機能分離型の電子写真感光体における静電潜像形成のメカニズムは次の通りである。すなわち、感光体を帯電した後、光照射すると、光は電荷発生材料により吸収され、光を吸収した電荷発生材料は電荷担体を発生し、この電荷担体は電荷輸送層に注入され、帯電によって生じている電界にしたがって電荷輸送層(ないしは感光層)中を移動し、感光体表面の電荷を中和することにより静電潜像が形成される。
そして、このようにして感光体表面に形成された静電潜像はトナーなどの現像剤によって可視画像化され、その画像を紙などに転写することにより複写或いは記録画像が得られる。
電子写真感光体には、感度、受容電位、電位保持性、電位安定性、残留電位、分光特性などに代表される電子写真特性、耐摩耗性等の機械的耐久性、および熱、光、放電生成物等に対する化学的安定性などの種々の特性が要求され、とりわけ、高感度で繰り返し安定性に優れていることが重要である。
従来から、機能分離型の電子写真感光体に用いる電荷発生材料や電荷輸送材料が種々開発されており、適切な電荷発生材料と電荷輸送材料の組合せによりある程度の高感化が達成されているが、電子写真感光体を多数回繰り返し使用すると帯電電位の低下、感度の低下、残留電位の上昇などが発生し、また感光層の膜剥がれやクラックの発生など感光層膜が劣化し複写或いは記録画像の画像欠陥や地汚れが発生する等、繰り返し安定性が不十分である。
【0003】
【発明が解決しようとする課題】
そこで、本発明の課題はこのような問題点を解決し、高感度であり、且つ多数回繰り返し使用しても帯電電位の低下、感度の低下、残留電位の上昇などの発生が少なく、また感光層膜の劣化がなく複写或いは記録画像の画像欠陥や地汚れの発生のない、繰り返し安定性に優れた電子写真感光体を提供することにある。
【0004】
【課題を解決するための手段】
本発明の上記課題は、導電性支持体上に少なくとも下記一般式(1)で示される化合物と下記一般式(14)で示される化合物の1種とを含有する感光層を設けてなることを特徴とする電子写真感光体によって達成される。

本発明によれば、感光層に上記特定の化合物の組合せを電荷輸送材料として用いることにより、高感度であり、且つ多数回繰り返し使用しても帯電電位の低下、感度の低下、残留電位の上昇などの発生が少なく、また感光層の膜剥がれやクラックの発生などのような感光層膜の劣化がなく複写或いは記録画像の画像欠陥や地汚れの発生のない、繰り返し安定性に優れた電子写真感光体を得ることができる。上記一般式(1)で示される化合物および一般式(14)で示される化合物は、例えば特開平2−272569号公報、特開平2−272570号公報などに開示されているが、上記のような特定の組み合わせで用いることにより上記のような感光層の劣化に基づく画像欠陥の発生を抑制する効果が生じることは見いだされていなかった。

本発明の電子写真感光体には、導電性支持体11と感光層との間に下引き層を設けることができる。下引き層は一般に樹脂を主成分とするが、これらの樹脂はその上に感光層を溶剤でもって塗布することを考えると、一般の有機溶剤に対して耐溶解性の高い樹脂であることが望ましい。このような樹脂としては、ポリビニルアルコール、カゼイン、ポリアクリル酸ナトリウム等の水溶性樹脂、共重合ナイロン、メトキシメチル化ナイロン等のアルコール可溶性樹脂、ポリウレタン、メラミン樹脂、アルキッド−メラミン樹脂、エポキシ樹脂等、三次元網目構造を形成する硬化型樹脂などが挙げられる。
また、下引き層にはモアレ防止、残留電位の低減等のために酸化チタン、シリカ、アルミナ、酸化ジルコニウム、酸化スズ、酸化インジウム等で例示できる金属酸化物の微粉末を加えてもよい。これらの下引き層は、前述の感光層のごとく適当な溶媒、塗工法を用いて形成することができる。
更に下引き層として、シランカップリング剤、チタンカップリング剤、クロムカップリング剤等を使用して、例えばゾル−ゲル法等により形成した金属酸化物層も有用である。この他に、本発明の下引き層にはAl23を陽極酸化にて設けたものや、ポリパラキシリレン(パリレン)等の有機物や、SiO、SnO2、TiO2、ITO、CeO2等の無機物を真空薄膜作製法にて設けたものも良好に使用できる。下引き層の膜厚としては5μm以下が適当である。
【0213】
また、本発明の電子写真感光体には、感光層保護の目的で、感光層の上に保護層を設けてもよい。これに使用される材料としては、ABS樹脂、ACS樹脂、オレフィン−ビニルモノマー共重合体、塩素化ポリエーテル、アリル樹脂、フェノール樹脂、ポリアセタール、ポリアミド、ポリアミドイミド、ポリアクリレート、ポリアリルスルホン、ポリブチレン、ポリブチレンテレフタレート、ポリカーボネート、ポリエーテルスルホン、ポリエチレン、ポリエチレンテレフタレート、ポリイミド、アクリル樹脂、ポリメチルペンテン、ポリプロピレン、ポリフェニレンオキシド、ポリスルホン、AS樹脂、AB樹脂、BS樹脂、ポリウレタン、ポリ塩化ビニル、ポリ塩化ビニリデン、エポキシ樹脂等の樹脂が挙げられる。
保護層にはその他、耐摩耗性を向上させる目的で、ポリテトラフルオロエチレンのようなフッ素樹脂、シリコーン樹脂およびこれら樹脂に酸化チタン、酸化スズ、チタン酸カリウム等の無機材料を分散したもの等を添加することができる。保護層の形成法としては、通常の塗布法が採用される。なお、保護層の厚さは、0.5〜10μm程度が適当である。また、以上のほかに真空薄膜作製法にて形成したi−C、a−SiCなど公知の材料も保護層として用いることができる。
【0214】
さらに、本発明の電子写真感光体には、感光層と保護層との間に別の中間層を設けることもできる。中間層には、一般にバインダー樹脂を主成分として用い、これら樹脂としては、ポリアミド、アルコール可溶性ナイロン、水溶性ポリビニルブチラール、ポリビニルブチラール、ポリビニルアルコールなどが挙げられる。
中間層の形成法としては、前述のごとく通常の塗布法が採用される。なお、中間層の厚さは0.05〜2μm程度が適当である。

上記の実施例及び比較例で得られた各電子写真感光体について、特開昭60−100167号公報に開示されている評価装置を用い、次のようにして感光体特性の測定を行なった。
コロナ放電電圧−6.0kV(または+5.6kV)で帯電20秒後の電位Vm(V)、暗減衰20秒後の電位Vo(V)、電位Voを1/2に減衰させるのに必要な露光量E1/2(lux・sec)を測定した。電位保持率=Vo/Vmと定義する。また、各電子写真感光体を電子写真複写機(FT−3300、リコー社製、ないしは感光体を正帯電できるように改造したもの)に搭載して連続3万枚の複写を行い、画像欠陥(異常画像)の有無を目視により判定した。また、複写試験終了後の各電子写真感光体について、上記と同じ方法によりVm(V)、Vo(V)、E1/2(lux・sec)を測定した。その結果を表29に示す。

BACKGROUND OF THE INVENTION
The present invention relates to an electrophotographic photosensitive member, and more specifically, an electron having a high sensitivity, excellent electrostatic characteristics and image characteristics in repeated use, and excellent repeat stability, which is used in combination with a specific charge transport material. The present invention relates to a photographic photoreceptor.

[Prior art]
In an organic electrophotographic photosensitive member, a function-separated type electrophotographic photosensitive member having a photosensitive layer containing a charge generating material and a charge transporting material in order to increase the sensitivity, in particular, a charge generating layer containing a charge generating material; A function-separated type electrophotographic photosensitive member in which a charge transport layer containing a charge transport material is laminated has been attracting attention and put into practical use. The mechanism of electrostatic latent image formation in this function-separated electrophotographic photosensitive member is as follows. That is, when the photoconductor is charged and then irradiated with light, the light is absorbed by the charge generation material, and the charge generation material that has absorbed the light generates charge carriers, which are injected into the charge transport layer and generated by charging. The electrostatic latent image is formed by moving in the charge transport layer (or photosensitive layer) according to the applied electric field and neutralizing the charge on the surface of the photoreceptor.
The electrostatic latent image formed on the surface of the photoreceptor in this way is visualized with a developer such as toner, and a copy or recorded image is obtained by transferring the image onto paper or the like.
Electrophotographic photoreceptors have electrophotographic characteristics such as sensitivity, receptive potential, potential retention, potential stability, residual potential, spectral characteristics, mechanical durability such as abrasion resistance, and heat, light, and discharge. Various characteristics such as chemical stability for products and the like are required, and in particular, it is important to have high sensitivity and excellent repeated stability.
Conventionally, various charge generation materials and charge transport materials for use in function-separated type electrophotographic photoreceptors have been developed, and a certain degree of sensitivity has been achieved by a combination of appropriate charge generation materials and charge transport materials. Repeated use of an electrophotographic photoreceptor many times causes a decrease in charging potential, a decrease in sensitivity, an increase in residual potential, etc., and the photosensitive layer film deteriorates due to film peeling or cracking of the photosensitive layer, resulting in copying or recording images. Repeated stability is insufficient, such as image defects and background stains.
[0003]
[Problems to be solved by the invention]
Therefore, the object of the present invention is to solve such problems and to have high sensitivity, and even when used repeatedly many times, the occurrence of a decrease in charging potential, a decrease in sensitivity, an increase in residual potential, etc. is small, and a photosensitive It is an object of the present invention to provide an electrophotographic photosensitive member excellent in repetitive stability, in which there is no deterioration of a layer film and no image defects or background stains occur in a copied or recorded image.

(14) It is achieved by an electrophotographic photoreceptor characterized by comprising a photosensitive layer containing one of the compounds represented by formula (1).
