CONSTITUTION:The electrophotographic sensitive body is obtained by forming on a conductive substrate 1 a single photosensitive layer 4 contg. a charge generating material 7 and as the charge transfer material the triphenylamine deriv. represented by the formula shown on the right in which R<1>, R<2>, R<3> are each H, alkyl, alkoxy, dialkylamino, diarylamino, diaralkylamino, OH, CN, halogen, ester, or NH2; R<4> is H, aryl, CN, or halogen; and l, m, n are each 1-5. The electrophotographic sensitive body may be obtained by forming the charge transfer layer 3 contg. said triphenylamine deriv. and the charge generating layer 2 on the conductive substrate 1 to form a functionally separated laminated type photosensitive layer 4, thus permitting the obtained photosensitive body to be stabilized in electrophotographic characteristics at the time of repeated uses and freed of toxicity problems.

ある。(Prior Art) Conventionally, electrophotographic photoreceptors (hereinafter sometimes simply referred to as photoreceptors) have been made of selenium, zinc oxide, cadmium sulfide,
Inorganic photoreceptors having a photosensitive layer mainly composed of an inorganic photoconductive compound such as silicon have been widely used. However, these are not necessarily satisfactory in terms of sensitivity, thermal stability, moisture resistance, durability, etc. For example, when selenium crystallizes, its properties as a photoreceptor deteriorate, making it difficult to manufacture.Also, selenium crystallizes due to heat, fingerprints, etc., and its performance as a photoreceptor deteriorates. In addition, cadmium sulfide has problems with moisture resistance and durability, and zinc oxide has problems with durability, etc.

ンを含有する感光層を有する有機感光体の記載がある。In order to overcome these drawbacks of inorganic photoreceptors, research and development have been actively conducted in recent years on organic photoreceptors having photosensitive layers containing various organic photoconductive compounds as main components. For example, Japanese Patent Publication No. 50-10496 describes an organic photoreceptor having a photosensitive layer containing poly-N-vinylcarbashield 2.4.7-)dinitro-9-fluorenone.

ることから多くの研究がなされてきた。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 higher performance by assigning the carrier generation function and the carrier transport function to different substances. Many studies have been conducted on such so-called function-separated type photoreceptors because each material can be selected from a wide range and a photoreceptor having arbitrary performance can be produced relatively easily.

る。As a result, various azo compounds have been developed and put into practical use as carrier-generating substances. On the other hand, regarding carrier transport substances, for example, JP-A-51-94829, JP-A-5
A wide variety of substances have been proposed, as disclosed in Japanese Patent Application Laid-open No. 2-72231, Japanese Patent Application Laid-Open No. 53-27033, Japanese Patent Application Laid-open No. 55-52063, and Japanese Patent Application Laid-Open No. 58-65440.

望まれていた。Although some electrophotographic photoreceptors made using carrier transport materials such as those described above exhibit relatively excellent electrophotographic performance, their durability against light or electrical loads is weak, and their durability during repeated use is poor. It does not fully satisfy practical requirements because it causes instability and deterioration of performance.
It has been desired to develop a carrier transport material that has even better carrier transport function and exhibits stable performance over long periods of use.

た。Furthermore, in recent years Ar laser and He-N have been used as light sources for photoreceptors.
Gas lasers and semiconductor lasers such as @V-zer are beginning to be used. These lasers are characterized by being capable of 0N10FF in time series, and are particularly promising as a light source for copiers with image processing functions, such as intelligent copiers, and printers for computer output. Among these, semiconductor lasers are attracting attention because their nature does not require electrical signal/optical signal conversion elements such as acoustic engineering elements, and they can be made smaller and lighter. However, this semiconductor laser has a low output compared to a gas laser, and the oscillation wavelength is also long (approximately 780 nm or more), so the spectral sensitivity of conventional photoreceptors is too high on the short wavelength side. It is difficult to apply to devices that use lasers as light sources;
New improvements were also required for carrier transport materials.

A photosensitive layer 4 made of a laminate with a carrier transport layer 3 containing a substance as a main component is provided. As shown in FIGS. 3 and 4, the photosensitive layer 4 may be provided on the conductive support 1 via an intermediate layer 5. When the photosensitive layer 4 has a two-layer structure in this manner, an electrophotographic photoreceptor having the most excellent electrophotographic properties can be obtained. Further, in the present invention, as shown in FIGS. 5 and 6, a photosensitive layer 4 formed by dispersing a carrier generating substance 7 in the form of fine particles in a layer 6 mainly composed of the carrier transporting substance is used as a conductive support. It may be provided directly on 1 or via an intermediate layer 5. Alternatively, instead of using a carrier-generating substance, a sensitizing dye or Lewis acid is added to a carrier-transporting substance, as shown in Figures 5 and 6.
Preferable results can also be obtained by providing a single photosensitive layer 4 as shown in the figure.

That is, when forming a negatively charged photosensitive layer, it is advantageous to use the carrier transport layer 3 as an upper layer, because the styryl triphenylamine derivative in the carrier transport layer 3 has a high transport ability for holes. This is because it is a substance that has
