[Industrial Field of Application] The present invention relates to an electrophotographic photoreceptor, and more particularly to an electrophotographic photoreceptor having a photosensitive layer containing an indoline compound on a conductive support. [Prior Art] Conventionally, inorganic photoconductive substances such as selenium, cadmium sulfide, and zinc oxide have been widely used in the photosensitive layer of electrophotographic photoreceptors. In recent years, research on organic photoconductive materials has progressed, and some have been put into practical use as electrophotographic photoreceptors. Organic photoconductive substances have advantages over inorganic photoconductive substances in that they are lightweight, easy to form into films, and easy to manufacture photoreceptors. Many studies have been conducted on photoconductive polymers such as polyvinylcarbazole as organic photoconductive substances, but these polymers alone have poor film properties, flexibility, and adhesion, and it is difficult to improve these shortcomings. For this purpose, plasticizers, binders, etc. are added, but these tend to cause other problems such as a decrease in sensitivity and an increase in residual potential, making it extremely difficult to put them into practical use. On the other hand, for organic low-molecular photoconductive substances, if a polymer with excellent film properties, flexibility, and adhesive properties is selected as a binder, a photoreceptor with excellent mechanical properties can be easily obtained. It has been difficult to find compounds suitable for making highly sensitive photoreceptors. In addition, low-molecular stilbene compounds described in JP-A-59-151157 exhibit high sensitivity initially, but when attached to a copying machine and repeatedly outputting images, the stilbene compounds cause ozonation and photodeterioration. As a result, the image quality deteriorates and only blurred images are obtained. [Problems to be Solved by the Invention] The purpose of the present invention is to eliminate the various drawbacks of the conventional photoreceptors mentioned above, and to meet the requirements of electrophotographic photoreceptors such as high sensitivity, high durability, and high modification. Every time,
An object of the present invention is to provide an electrophotographic photoreceptor that fully satisfies all conditions for high image quality. [Means for Solving Problems and Effects] The present invention comprises an electrophotographic photoreceptor characterized in that a photosensitive layer containing an indoline compound represented by the following general formula is provided on a conductive support. general formula In the formula, A represents a hydrogen atom, an aliphatic hydrocarbon group, an aromatic hydrocarbon group which may have a substituent, or an aromatic heterocyclic group, R 1 , R 2 , R 3 , R 4 , R 5 and R6
each independently represents a hydrogen atom, a halogen atom, a nitro group, an alkyl group that may have a substituent, an aralkyl group, or an aryl group, and R 5 and
R 6 may form a ring. The present invention will be specifically explained below. The electrophotographic photoreceptor of the present invention contains an indoline compound represented by the above general formula in the photosensitive layer. In the general formula, A is a hydrogen atom, methyl,
Ethyl, linear or branched alkyl groups such as propyl, butyl, pentyl, benzene, naphthalene, anthracene, pyrene, acenaphthene,
These are aromatic hydrocarbon groups derived from fluorene, etc., and aromatic heterocyclic groups derived from pyridine, pyrrole, pyrazole, dibenzofuran, carbazole, etc., and these aromatic hydrocarbon groups and aromatic heterocyclic groups are substituents. Substituents include alkyl groups such as methyl and ethyl, halogen atoms such as chlorine and bromine, alkoxy groups such as methoxy and ethoxy, aryloxy groups such as phenoxy, and dimethylamino and diethylamino. alkylamino group, methylthio,
Examples include alkylthio groups such as ethylthio. R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are hydrogen atoms, halogen atoms such as chlorine atoms, bromine atoms, nitro groups, methyl, ethyl, linear or branched propyl, butyl, pentyl , aralkyl groups such as benzyl, phenethyl, and aryl groups such as phenyl, naphthyl, and anthryl. These alkyl groups, aralkyl groups, and aryl groups may have a substituent, and the substituent is methyl. , alkyl groups such as ethyl, halogen atoms such as chlorine atom and bromine atom, alkoxy groups such as methoxy and ethoxy, aryloxy groups such as phenoxy, alkylamino groups such as dimethylamino and diethylamino, alkylthio groups such as methylthio and ethylthio, etc. can be mentioned. Furthermore, R 5 and R 6 may form a ring. Typical specific examples of the indoline compound represented by the above general formula are listed below. However, the indoline compound represented by the above general formula is not limited thereto. The electrophotographic photoreceptor of the present invention has a photosensitive layer containing one or more indoline compounds represented by the above general formula. There are various forms of the photosensitive layer of the electrophotographic photoreceptor, and the photosensitive layer of the electrophotographic photoreceptor of the present invention may be any of them. As examples, FIGS. 1, 2, and 3 are partial sectional views showing the structure of the electrophotographic photoreceptor of the present invention. In the electrophotographic photoreceptor shown in FIG. 1, a photosensitive layer 2 comprising an indoline compound represented by the above general formula (hereinafter referred to as an indoline compound), a sensitizing dye or an electron-withdrawing compound, and a binder is provided on a conductive support 1. It is something that The electrophotographic photoreceptor shown in FIG. 2 has a photosensitive layer 2' on a conductive support 1, in which a charge carrier generating substance 3 is dispersed in a charge transfer medium 4 made of an indoline compound and a binder. . The electrophotographic photoreceptor shown in FIG. 3 has a photosensitive layer 2'' consisting of a charge carrier generation layer 5 and a charge transfer layer 4 containing an indoline compound on a conductive support 1. In a photographic photoreceptor, an indoline compound acts as a photoconductive substance, and the generation and transfer of charge carriers necessary for light attenuation occur through the indoline compound.The absorption of many indoline compounds occurs at low wavelengths in the ultraviolet to visible range. Therefore, in order to form an image with visible light, it is necessary to add a sensitizing dye that absorbs in the visible region or to add an electron-withdrawing compound to form a charge transfer complex to sensitize. In the electrophotographic photoreceptor shown in FIGS. 2 and 3, a charge carrier generating substance generates charge carriers in response to light, and the charge carriers are transferred by a charge transfer medium (mainly an indoline compound). To create the electrophotographic photoreceptor shown in the figure, an indoline compound and a binder are dissolved in a solvent, a sensitizing dye or an electron-withdrawing compound is added as needed, and the material is coated on a conductive support and dried. To create the electrophotographic photoreceptor shown in FIG. A charge carrier generating substance is vacuum deposited on a conductive support, or a dispersion obtained by dispersing fine particles of a charge carrier generating substance in a solvent dissolved in a binder as necessary is coated, dried, and It is created by coating a solution containing an indoline compound and a binder on top and drying it.A roll coater, wire bar, doctor blade, etc. is usually used for coating.The thickness of the photosensitive layer is shown in Figures 1 and 2. In the case of the figure,
It is 3-50μ, preferably 5-20μ. In the case of Figure 3, the thickness of the charge carrier generation layer is
The thickness of the charge transfer layer is 0.5-5μ, preferably 1-2μ, and the thickness of the charge transport layer is 3-50μ, preferably 5-20μ. In the electrophotographic photoreceptor shown in FIG. 1, the ratio of the indoline compound in the photosensitive layer is 10 to
70% by weight, preferably 30-50% by weight. The sensitizing dye used to impart photosensitivity in the visible region is preferably 0.1 to 5% by weight based on the photosensitive layer.
It is 0.5 to 3% by weight. The electron-withdrawing compound is added in an amount of 0.1 to 50% by weight, preferably 5 to 30% by weight, based on the photosensitive layer. In the electrophotographic photoreceptor shown in Figure 2, the ratio of the indoline compound in the photosensitive layer is 10 to 90% of the photosensitive layer.
% by weight, preferably 10 to 60% by weight, and the charge carrier generating substance is 1 to 50% by weight, based on the photosensitive layer.
Preferably it is 3 to 20% by weight. The proportion of the indoline compound in the charge transfer layer in the electrophotographic photoreceptor shown in FIG. 3 is 10 to 95% by weight, preferably 10 to 60% by weight. In addition, in producing any of the electrophotographic photoreceptors shown in FIGS. 1 to 3, a plasticizer and a sensitizer can be used together with a binder. In the electrophotographic photoreceptor of the present invention, the conductive support may be, for example, a metal plate or foil made of aluminum or the like, a plastic film deposited with a metal such as aluminum, or paper subjected to conductive treatment. As a binder, vinyl polymers such as polystyrene, polyacrylamide, poly-N-vinylcarbazole, polyamide, polyester,
Condensation resins such as epoxy resins, phenoxy resins, and polycarbonates are used, but any resin that is insulating and adhesive to the support can be used. As the sensitizing dye, electron-withdrawing compound, and charge carrier generating substance used in the photosensitive layer, well-known ones can be used. Examples of the sensitizing dye include triphenylmethane dyes such as methyl violet, brilliant green, and crystal violet, thiazine dyes such as methylene blue, cyanine dyes, and pyrylium dyes. Examples of electron-withdrawing compounds include quinones such as chloranil, 1-nitroanthraquinone, and 2-chloroanthraquinone, aldehydes such as 2-chlorobenzaldehyde and 4-nitrobenzaldehyde, 3,5-dinitrobenzophenone,
2,4,7-trinitrofluorenone, 2,4,
Examples include ketones such as 5,7-tetranitrofluorenone, acid anhydrides such as phthalic anhydride, and cyano compounds. Charge carrier generating substances include selenium, selenium-tellurium alloys, selenium-arsenic alloys, inorganic photoconductive substances such as cadmium sulfide, copper phthalocyanine, azo pigments, disazo pigments, trisazo pigments,
Examples include organic photoconductive substances such as cyanine pigments, anthraquinone pigments, perylene pigments, pyrylium salts, thioindigo, and quinacridone. Furthermore, a well-known plasticizer may be contained in order to improve the film formability, flexibility, and mechanical strength of the photoreceptor. Examples of plasticizers include aromatic compounds such as phthalic esters, phosphoric esters, halogenated paraffins, and methylnaphthalene. Further, in the electrophotographic photoreceptor produced as described above, an adhesive layer or a barrier layer can be provided between the conductive support and the photosensitive layer, if necessary. Materials for these layers include polyamide, nitrocellulose, aluminum oxide, etc., and the film thickness is preferably 1 μm or less. The electrophotographic photoreceptor of the present invention has extremely high sensitivity;
It has excellent advantages such as small accumulation of residual potential and small fluctuations in surface potential and sensitivity due to repeated use, excellent durability, and high flexibility. In particular, the image quality is high and durable, with no blurring even after repeated durability tests. [Example] Example 1 2 parts of Chlordiane Blue, 1 part of polyester (isoptalic acid-ethylene glycol condensate, Mn=30000), 97 parts of tetrahydrofuran, and the above components were ground and mixed in a ball mill to obtain a charge carrier generating material dispersion. This was applied with a wire bar onto a polyester film on which aluminum was vapor-deposited, and dried to form a charge carrier generation layer with a thickness of 1 μm. On this charge carrier generation layer, 10 parts of the indoline compound of the above-mentioned exemplary compound (10) and polycarbonate (bisphenol A-phosgene condensate, Mn=
A charge transfer layer was formed by coating a coating solution prepared by dissolving 10 parts of 28000) in 80 parts of tetrahydrofuran so that the film thickness after drying was 15 μm, and an electrophotographic photoreceptor was prepared. Let it be a photoreceptor (1). The photoreceptor (1) was tested at -5KV using a commercially available electrostatic copying paper testing device (KK Kawaguchi Electric Seisakusho SP428).
After charging by corona discharge for 20 seconds before and after, leave it in a dark place for 20 seconds and measure the surface potential at that time.
600V, then irradiate the photoreceptor surface with tungsten lamp light so that the illumination intensity is 10 lux, find the time (seconds) until the surface potential reaches 300V, and find the exposure sensitivity E1/2 (lux, seconds). Calculated. The results will be described later. This photoreceptor (1) is used in an electrophotographic copying machine (product name NP-).
