優れた光感度、耐久性を有する新規な電子写真感光体を
提供するものである。The present invention provides a novel electrophotographic photoreceptor having excellent photosensitivity and durability.
(従来の技術)
電子写真法は既にカールソンが米国特許第2.297.
691号に明らかにしたように、この写真法は静電現象
と光導電現象とを巧妙に組合せしたものであり、光導電
性感光体を暗所でコロナ放電等により。(Prior Art) The electrophotographic method has already been published by Carlson in US Patent No. 2.297.
As disclosed in No. 691, this photographic method is an ingenious combination of electrostatic and photoconductive phenomena, in which a photoconductive photoreceptor is exposed in the dark by corona discharge or the like.
表面を一様に帯電させた後、光導電性を利用して光像を
静電潜像に変え、これに着色した電荷粉体(トナー)を
付着させて可視像に変える画像形成法の一つである。An image forming method that uses photoconductivity to uniformly charge the surface and then convert the optical image into an electrostatic latent image, which is then converted into a visible image by attaching colored charged powder (toner) to it. There is one.
このような電子写真法における感光体に要求される基本
的な電気的および光電気的特性として、暗所において適
当な電位に帯電できること、この電位が適当な時間保持
できること、更に、光照射により速やかに電荷が逸散す
ることができることなどがあげられる。The basic electrical and photoelectric properties required of a photoreceptor in such electrophotography are that it can be charged to an appropriate potential in a dark place, that this potential can be maintained for an appropriate amount of time, and that it can be charged quickly by light irradiation. For example, the electric charge can be dissipated.
このような感光体において、従来より、無定形セレン、
硫化カドミウム、酸化亜鉛等の無機光導電性物質が広く

光体として用いられるが。In such photoreceptors, amorphous selenium,
Inorganic photoconductive materials such as cadmium sulfide and zinc oxide have been widely used. Although these inorganic materials satisfy the above conditions, they also have some drawbacks. For example, cadmium sulfide or zinc oxide is used as a photoreceptor by dispersing it in a resin as a binder.
平滑性、可撓性、硬度、引張り強度、耐摩擦性などの機
械的な欠点を有するため、そのままでは反復使用に耐え
ることができない。更に硫化カドミウムにおいては衛生
性の問題にも考慮が必要である。Since it has mechanical defects such as smoothness, flexibility, hardness, tensile strength, and abrasion resistance, it cannot withstand repeated use as it is. Furthermore, when using cadmium sulfide, consideration must also be given to hygiene issues.
また、無定形セレンにおいては、製法が蒸着によらなく
てはならず、!!造ココスト高価となるばかりでなく、
可撓性がな(、ベルト状に加工することが困難である他
、セレンの毒性および熱や機械的衝撃に対して鋭敏なた
め取り扱いには注意を要するなどの欠点を有する。In addition, for amorphous selenium, the manufacturing method must be based on vapor deposition! ! Not only is the manufacturing cost expensive, but
It has disadvantages such as being difficult to process into a belt shape, as well as being sensitive to heat and mechanical shock due to the toxicity of selenium, so it must be handled with care.
近年、これらの無機系感光体の欠点を排除するために、
有機系感光体の研究がすすみ、有機系感光体における。In recent years, in order to eliminate the drawbacks of these inorganic photoreceptors,
Research on organic photoreceptors is progressing, and organic photoreceptors.

質の組合せにより、その特性はより良好となり、有用な
感光体が提供される。Furthermore, electrophotographic photoreceptors have been proposed that combine a substance that generates carriers when exposed to light (called a carrier-generating substance) and a substance that can transport the generated carriers (called a carrier-transporting substance). . For example, U.S. Pat. No. 3.791.826 discloses a photoreceptor in which a carrier transport layer is provided on a carrier generation layer, and U.S. Pat. Photoreceptors have been described that have a photosensitive layer dispersed in a transport material. By assigning the functions of this type of carrier generation and carrier transport to separate substances, that is, by combining the carrier generation substance and the carrier transport substance, the characteristics can be improved and a useful photoreceptor can be provided. be done.

055. Japanese Unexamined Patent Publication No. 58-147746 and the like are already known. However, these azo compounds do not necessarily fully satisfy the characteristics such as sensitivity, residual potential, or stability during repeated use, and the wide range of requirements for electrophotographic processes such as the limited selection range of carrier transport materials The reality is that nothing that completely satisfies these requirements has yet been found.
