〔産業上の利用分野〕
本発明は電子写真感光体に関し、特に有機光導電性電子
写真感光体の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to electrophotographic photoreceptors, and more particularly to improvements in organic photoconductive electrophotographic photoreceptors.
カールソン方法の電子写真複写機においては、感光体表
面に帯電させた後、露光によって静電潜像を形成し、そ
の静電潜像をトナーによって現像し、次いでその可視像
を紙等に転写、定着させる。In an electrophotographic copying machine using the Carlson method, the surface of a photoreceptor is charged, an electrostatic latent image is formed by exposure, the electrostatic latent image is developed with toner, and the visible image is then transferred to paper, etc. , make it established.
一方、感光体には付着トナーの除去や除電、表面の清浄
化が施され、長期に亘って反復使用される。On the other hand, the photoreceptor is subjected to removal of adhered toner, neutralization of static electricity, and surface cleaning, and is used repeatedly over a long period of time.
従って、電子写真感光体としては、帯電特性および感度

加えて繰返し使用での耐剛性、耐摩耗性、耐湿性等の物
理的性質や、コロナ放電時に発生するオゾン、露光時の
紫外線等への耐性(耐環境性)においても良好であるこ
とが要求される。Therefore, as an electrophotographic photoreceptor, it not only has good charging characteristics and sensitivity, but also has electrophotographic characteristics such as low dark decay.
In addition, it is required to have good physical properties such as rigidity resistance, abrasion resistance, and moisture resistance during repeated use, as well as resistance to ozone generated during corona discharge, ultraviolet rays during exposure, etc. (environmental resistance). be done.
従来、電子写真感光体としては、セレン、酸化亜鉛、硫
化カドミウム等の無機光導電性物質を主成分とする感光
体層を有する無機感光体が広く用いられている。Conventionally, inorganic photoreceptors having a photoreceptor layer containing an inorganic photoconductive substance such as selenium, zinc oxide, or cadmium sulfide as a main component have been widely used as electrophotographic photoreceptors.
一方、種々の有機光導電性物質を電子写真感光体の感光
体層の材料として利用することが近年活発に研究、開発
されている。On the other hand, the use of various organic photoconductive substances as materials for photoreceptor layers of electrophotographic photoreceptors has been actively researched and developed in recent years.
例えば特公昭5Q−10496号には、ポリ−N−ビニ
ルカルバゾールと2.4.7−ドリニトロー9−フルオ
レノンを含有した感光体層を有する有機感光体について
記載されている。しかしこの感光体は、感度及び耐久性
において必ずしも満足できるものではない。このような
欠点を改善するために、感光体層において、電荷り生機
能と電荷輸送機能とを異なる物質に個別に分担させるこ
とにより、感度が高くて耐久性の大きい有機感光体を開
発する試みがなされている。このようないわば機能分離
型の電子写真感光体においては、各機能を発揮する物質
を広い範囲のものから選択することができるので、任意
の特性を有する電子写真感光体を比較的容易に作製する
ことが可能である。For example, Japanese Patent Publication No. 5Q-10496 describes an organic photoreceptor having a photoreceptor layer containing poly-N-vinylcarbazole and 2,4,7-dolinitro-9-fluorenone. However, this photoreceptor is not necessarily satisfactory in sensitivity and durability. In order to improve these shortcomings, an attempt was made to develop an organic photoreceptor with high sensitivity and durability by assigning the charge generation function and charge transport function to different substances in the photoreceptor layer. is being done. In such so-called function-separated type electrophotographic photoreceptors, substances that exhibit each function can be selected from a wide range of materials, so it is relatively easy to produce electrophotographic photoreceptors with arbitrary characteristics. Is possible.
こうした機能分離型の電子写真感光体に有効な電荷発生
物質として、従来数多くの物質が提案されている。無機
物質を用いる例としては、例えば特公昭43−1819
8号に記載されているように、無定形セレンがある。こ
れは有機電荷輸送物質と組合される。Many substances have been proposed as charge-generating substances that are effective for such functionally separated electrophotographic photoreceptors. Examples of using inorganic substances include, for example, Japanese Patent Publication No. 43-1819
As described in No. 8, there is amorphous selenium. This is combined with an organic charge transport material.
また、有機染料や有機顔料を電荷発生物質として用いた
電子写真感光体も多数提案されており、例えば、ビスア
ゾ化合物を含有する感光体層を有するものは、特開昭4
7−37543号、同55−22834号、同54−7
9632号、同56−116040号等により既に知ら
れている。In addition, many electrophotographic photoreceptors using organic dyes or organic pigments as charge-generating substances have been proposed. For example, one having a photoreceptor layer containing a bisazo compound was published in
No. 7-37543, No. 55-22834, No. 54-7
It is already known from No. 9632, No. 56-116040, etc.
ところで、有機光導電性物質を用いる公知の感光体は通
常、負帯電用として使用されている。この理由は、負帯
電使用の場合には、電荷のうちホールの移動度が大きい
ことから、光感度等の面で有利なためである。By the way, known photoreceptors using organic photoconductive substances are generally used for negative charging. The reason for this is that when negative charging is used, the mobility of holes among the charges is large, which is advantageous in terms of photosensitivity and the like.
しかしながら、このような負帯電使用の場合の問題は、
帯電器による負帯電時に雰囲気中にオゾンが発生し易く
なり、環境条件を悪くしてしまう。However, the problem with using such a negative charge is that
Ozone is likely to be generated in the atmosphere when negatively charged by the charger, worsening the environmental conditions.
また、負帯電用感光体の現像には正極性のトナーが必要
となるが、正極性のトナーは強磁性体電荷粒子に対する
摩擦帯電系列からみて製造が困難であることである。Further, a positive polarity toner is required for development of a negatively charged photoreceptor, but it is difficult to manufacture a positive polarity toner in view of the triboelectric charging sequence with respect to ferromagnetic charged particles.
そこで、有機光導電性物質を用いる感光体を正帯電で使
用する、例えば、電荷発生層上に電荷輸送層を積層し、
電荷輸送層を電子輸送能の大きい物質で形成する正帯電
感光体等が提案されている。Therefore, a photoreceptor using an organic photoconductive substance is used with positive charging, for example, a charge transport layer is laminated on a charge generation layer.
Positively charged photoreceptors and the like have been proposed in which a charge transport layer is formed of a material with a high electron transport ability.
しかしながら電荷輸送層に例えばトリニトロフルオレノ
ン等を含有せしめると、該物質が発癌性である等の問題
を提起することがある。他方、ホール輸送能の大きい電
荷輸送層上に電荷発生層を積層した正帯電感光体が考え
られるが、この機構では表面側に存在させる電荷発生層
を非常に薄くする必要があり、耐刷性等が悪くなり、実
用的な層構成ではない。However, if the charge transport layer contains, for example, trinitrofluorenone, problems may arise, such as that the substance is carcinogenic. On the other hand, a positively charged photoreceptor in which a charge generation layer is laminated on a charge transport layer with a high hole transport ability is considered, but with this mechanism, the charge generation layer on the surface side needs to be extremely thin, and printing durability may be affected. etc., and it is not a practical layer structure.

No. 4 shows a product containing a thiapyrylium salt (charge generating substance) so as to form a complex with polycarbonate (binder resin). However, this photoreceptor has disadvantages in that the memory phenomenon is large and ghosts are likely to occur. Further, U.S. Pat. No. 3,357.989 discloses a photoreceptor containing phthalocyanine,
The properties of phthalocyanine vary depending on the crystal type, and
It is necessary to strictly control the crystal type, and furthermore, the short wavelength sensitivity is insufficient and the memory phenomenon is large, making it unsuitable for copying machines that use light sources in the visible wavelength range.

れているが、いずれも光感度、メモリ現象又は労働衛生

改善すべき多くの問題点がある。Various attempts have been made to obtain positively charged photoreceptors, but all of them require improvements in terms of photosensitivity, memory phenomenon, occupational hygiene, etc., and durability such as ultraviolet resistance and ozone oxidation resistance. There are many problems.

。Therefore, from a functional standpoint, a laminated structure in which the upper layer (surface layer) is a charge generation layer containing a charge generation substance that generates holes and electrons when irradiated with light, and the lower layer is a charge transport layer containing a charge transport substance having a hole transport function. It is conceivable to make the photoreceptor the basic form of a photoreceptor for both positive and negative charging, and to supplement what is lacking.

体表面の正電荷を打消すための電子の移動が早くなり、
高感度特性が得られることが考えられる。In addition, in such a photoreceptor, if a charge generating substance having, for example, an electron-withdrawing group is used in the structure, the movement of electrons to cancel the positive charge on the surface of the photoreceptor becomes faster.
It is thought that high sensitivity characteristics can be obtained.

写真性能が劣化し、画質が低下するようになる。However, since the positively charged photoreceptor is formed with a layer containing a charge generating substance as a surface layer, it is vulnerable to external effects such as light irradiation, especially short wave light irradiation such as ultraviolet light, corona discharge, humidity, ozone oxidation, and mechanical friction. As a result, the electrophotographic performance deteriorates during the storage of the photoreceptor and during the image formation process, resulting in a decrease in image quality.
従来の電荷輸送層を表面層とする負帯電感光体において
は、前記各種の外部作用の影響は極めて少なく、むしろ
前記電荷輸送層が下層の電荷発生層を保護する作用を有
している。In a negatively charged photoreceptor having a conventional charge transport layer as a surface layer, the effects of the various external effects described above are extremely small, and rather the charge transport layer has the effect of protecting the underlying charge generation layer.

ねることはできない。Therefore, it is conceivable to provide a thin protective layer made of an insulating and transparent resin to protect the layer containing the charge-generating substance from external effects, but the protective layer may block the charges generated during light irradiation. The effect of light irradiation will be lost, and if the protective layer that forms the surface layer is thick, it will cause a decrease in sensitivity and will have little residual UV blocking effect. It cannot be left to the layers alone.

りの発生、画質の低下に陥る。In the electrophotographic process based on the Carlson process, a light source that generates ultraviolet rays is generally used for image exposure, erasing exposure, pre-transfer exposure, cleaning exposure, etc. Repeated irradiation with energetic ultraviolet light is sufficient to cleave the organic compound molecules used in the photoreceptor. That is, C forming the photoreceptor
GM, CTM, binders, etc. undergo radical dissociation, lose their original molecular structure, and deteriorate, resulting in deterioration of the photoreceptor. Specifically, it causes a decrease in sensitivity, an increase in residual potential, etc., and the occurrence of fogging. , the image quality deteriorates.

る場合、その影響は極めて大きい。The combined deterioration induced and derived from ultraviolet rays or ultraviolet rays and ozone in the photoreceptor is caused by various exposure treatments and corona discharge that are repeatedly applied, but it is also thought to be enhanced by singlet oxygen generated by exposure. Furthermore, the degree of combined deterioration caused by ultraviolet rays, etc. varies depending on the layer structure of the photoreceptor, the type of CGM or CTM, etc., but CTM
are more susceptible to deterioration, and the effect is particularly significant when organic photoconductive materials are used.

によると思われる。The stabilization mechanism of the compound according to the present invention, that is, a compound generally regarded as an ultraviolet absorber, against organic substances is as follows:
This is thought to be due to the fact that the decomposition energy possessed by ultraviolet light (sometimes referred to as UV) is transformed into vibrational energy within the UV absorber.
