Description
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。 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.
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。 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.
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。 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. Repeated stability is insufficient, such as image defects and background stains.
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。 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.

本発明によれば、感光層に電荷輸送材料して前記特定の2種類の化合物を組み合わせ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がない、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。 According to the present invention, by using a combination of the above two specific compounds as a charge transport material for the photosensitive layer, the sensitivity is high, and even when used repeatedly many times, the charged potential is decreased, the sensitivity is decreased, There is little increase in residual potential, and there is no deterioration of the photosensitive layer film such as film peeling or cracking of the photosensitive layer. An electrophotographic photoreceptor can be obtained.
