本発明は電子写真感光体に関し、特に有機光導電性電丘
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 particularly to improvements in organic photoconductive electrophotographic photoreceptors.
カールソ:/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 the electrophotographic copying machine of Carlso: / method, after the surface of the photoreceptor is charged, an electrostatic latent image is formed by exposure.
The electrostatic latent image is developed with toner, and then the visible image is transferred and fixed onto paper or the like.
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.

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 has good physical properties such as printing durability, abrasion resistance, and moisture resistance after repeated use, as well as resistance to ozone generated during corona discharge and ultraviolet rays during exposure (environmental resistance). required.

An organic photoreceptor having a photoreceptor layer containing fluorenone is described. However, this photoreceptor is not necessarily satisfactory in sensitivity and durability. In order to improve these drawbacks, attempts have been made to develop organic photoreceptors with high sensitivity and durability by assigning charge generation and charge transport functions to different materials in the photoreceptor layer. 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

物質を用いる例としては、例えば特公昭43−1619

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. 43-1619
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

9832号、同56−116040号等にJ−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 J-No. 9832, No. 56-116040, etc.
と二ろで、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。Known photoreceptors using organic photoconductive materials 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。二とである。Further, a toner of positive polarity is required for development of a negatively charged photoreceptor, but it is difficult to manufacture a toner of positive polarity in view of the triboelectrification series with respect to ferromagnetic charged particles. It is two.
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.

なり、実用的な層構成ではない。However, when the charge transport layer contains, for example, trinitrofluorenone, problems may arise such as the fact that the substance is carcinogenic. On the other hand, it may be possible to consider a positively charged photoreceptor in which a charge-generating layer is laminated on a charge-transporting layer with a large hole-transporting ability, but this mechanism requires that the charge-generating layer present on the surface side be extremely thin. Printing durability deteriorates, and this 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, with this photoreceptor,
The drawbacks are 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, but the characteristics of phthalocyanine vary depending on the crystal type, and

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.

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.

Specifically, it causes a decrease in sensitivity, an increase in residual potential, etc.7, fogging, and a decrease in image quality. fall into decline.

Derivative shear compound deterioration (J) is caused by various exposure treatments and discharges that are repeatedly added, but it is thought that the deterioration of the photoreceptor will not be strengthened even if it is exposed to single oxygen generated by exposure. Although the extent to which C'I' M is susceptible to deterioration due to ultraviolet rays, etc. varies depending on the layer structure of CGM and the type of CTM, etc., C'I' M is more susceptible to deterioration, especially organic photoconductive materials. The effects of using sexual substances are extremely large.

It has been found that it not only helps prevent IJ, but also contributes to improving other electrophotographic properties and physical properties.

ことによると思われる。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 residual decomposition energy of ultraviolet light (sometimes referred to as Uv) is transformed into vibrational energy within the LJV absorber.
