The present invention relates to a photoconductive composition mainly composed of an organic photoconductor and an electrophotographic photosensitive material using the same in an electrophotographic photosensitive layer, and more specifically to a photoconductive composition mainly composed of an organic photoconductor and a sulfonamide compound. The present invention relates to a sensitive photoconductive composition and a highly sensitive electrophotographic material using the same in an electrophotographic photosensitive layer. Conventionally, many organic compounds have been known as photoconductors for photosensitive compositions for electrophotography, and it has been confirmed that some of these compounds have considerably high photosensitivity. However, at present, there are very few examples of actually using organic photoconductors as electrophotographic materials. Organic photoconductors have many superior properties compared to inorganic photoconductors and offer a wide range of applications in the field of electrophotography. For example, it is only possible to produce transparent electrophotographic films, flexible electrophotographic films, lightweight and easy-to-handle electrophotographic films, etc. using organic photoconductors. In addition, organic photoconductors have properties that cannot be expected from inorganic photoconductors, such as film-forming ability during the production of electrophotographic photosensitive materials, surface smoothness, and selectivity of charging polarity in the electrophotographic process. has. Although organic photoconductors have excellent properties in many respects, the main reasons why they have not been able to fully contribute to the field of electrophotography to date are mainly their low photosensitivity and coatings. This is due to the fragility of Research on organic photoconductors initially focused on compounds such as low molecular weight heterocyclic compounds, nitrogen-containing aromatic compounds, and various polymeric aromatic compounds. As a result, some compounds with considerably high sensitivity have been found, but recently there has been a tendency to focus on research on sensitization methods in order to achieve even higher sensitivity. This is because, even though it is the most highly sensitive organic photosemiconductor compound known to date, it does not have enough sensitivity to be put to practical use as it is without sensitization treatment. Therefore, in the actual use of organic photoconductors, it is essential to select the most effective sensitization method, and the industrial value of organic photoconductors depends on the applied sensitization method. It is no exaggeration to say that it depends on how highly sensitive an electrophotographic light-sensitive material can be ultimately provided. The most commonly known methods of sensitization are the addition of sensitizing dyes and the addition of Lewis acids, which are applicable to most organic photoconductors. The former is achieved by adding the spectral absorption properties of a dye to an organic photoconductor, and the latter is achieved by the appearance of new spectral sensitivity due to the formation of a donor-acceptor complex with the organic photoconductor. It brings about sensitization. The present inventors have been searching for a method to sensitize organic photoconductors, and have discovered that adding a sulfonamide compound to a photoconductive composition significantly increases photosensitivity, leading to the present invention. did. A first object of the present invention is to provide a highly sensitized photoconductive composition. A second object of the present invention is to provide an electrophotographic material having high sensitivity. The present invention relates to a photoconductive composition containing an organic photoconductor and a sulfonamide compound represented by the following general formula (). R 1 : A monovalent group consisting of a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocycle. R 2 , R 3 : H, substituted or unsubstituted alkyl group,
A monovalent group consisting of a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocycle. The present invention also provides an electrophotographic photosensitive material comprising a photoconductive composition containing an organic photoconductor and a sulfonamide compound represented by the above general formula () on a support having at least an electrically conductive surface. The present invention relates to an electrophotographic material having layers. Although various organic photoconductors can be used in the present invention, organic photoconductors that can be dye-sensitized are preferred. The following can be mentioned as an example of an organic photoconductor. (i) Polymeric organic photoconductor: Polycyclic aromatic or heteroaromatic vinyl polymerized polymeric organic photoconductor containing π electrons. Naphthalene, anthracene, anthracene,

In the present invention, vinyl polymer homopolymers and copolymers containing these nuclei are used as photoconductors. For example, vinyl polymers such as polyvinylnaphthalene, polyvinylanthracene, polyvinylpyrene, polyvinylperylene, polyacenaphthylene, polystyrylanthracene, polyvinylcarbazole, polyvinylindole, polyvinylacridine, polyanthrylmethylvinyl ether, polypyrenylmethylvinyl ether, polycarbazoly vinyl ether polymers such as ethyl vinyl ether and polyindolyl ethyl vinyl ether; epoxy resins such as polyglycidyl carbazole, polyglycidyl indole, and poly-p-glycidyl anthrylbenzene;
