Abstract: An ink cartridge and an ink storage device including the same are provided, which has a stable quality, lower ink residue, less components, lower cost, and low impact to the environment. The ink storage device is assembled by an ink receiving portion, a sleeve, and a pin plug. The ink receiving portion is formed by welding and sealing the edges of a pair of plates. The sleeve has a first end portion and a respective second end portion. The first end portion is connected to the ink receiving portion and the second end portion exposes out of the ink receiving portion. An interior of the sleeve has a penetrating hole connecting the ink receiving portion. The pin plug is made of an elastic material and is installed to the second end portion of the sleeve. A storage portion for storing the ink is formed in the pin plug, and an end of the pin plug is formed as a linking hole linking the ink receiving portion with the storage portion through the penetrating hole.

Abstract: An electrophotography photoconductor has a conductive substrate and an anodic oxidation layer on which a photoconductive layer is formed. The sealed surface of the anodic oxidation has an admittance ranging from 0.4 S/m2 to 30 S/m2 and a contact angle of pure water ranging 30° to 80°. The surface of the anodic oxidation layer is sealed by dipping it into a nickel acetate solution. The contact angle and the admittance are determined depending on a temperature of the nickel acetate solution and a sealing time. In the case where the sealed surface is irradiated with ultraviolet rays, the heat-resisting property and cleanliness are improved.

Abstract: The electrophotographic photoreceptor according to the present invention has a conductive support (10) and a photoconductive layer laminated on the conductive support. The conductive layer is characterized by making a quantity of reflected lights with respect to exposure of a coherent light as a light source to be small and by having a short wavelength surface roughness in order to suppress a quantity of interference lights produced by the reflected lights and reflected lights from or incident lights on the photoconductive layer. Specifically, the conductive support (10) has aluminum or aluminum based alloy, and the maximum height (Ry) of the surface roughness of the conductive support is 0.8 &mgr;m or more and 2.0 &mgr;m or less. Further, the reflectivity of the light on the surface of the conductive support is equal to or less than 35% of a quantity of exposure light of a light source of a coherent light. This is able to prevent generation of the interference fringes.

Abstract: An electrophotography photoconductor has a conductive substrate and an anodic oxidation layer on which a photoconductive layer is formed. The sealed surface of the anodic oxidation has an admittance ranging from 0.4 S/m.sup.2 to 30 S/m.sup.2 and a contact angle of pure water ranging 30.degree. to 80.degree.. The surface of the anodic oxidation layer is sealed by dipping it into a nickel acetate solution. The contact angle and the admittance are determined depending on a temperature of the nickel acetate solution and a sealing time. In the case where the sealed surface is irradiated with ultraviolet rays, the heat-resisting property and cleanliness are improved.

Abstract: In the manufacture of a photoconductor for electrophotography, an aluminum substrate is heated at a temperature of 430.degree. C. to 550.degree. C. for three or more hours in such a manner that the admittance of an anodic oxidation film to be formed over the aluminum substrate is within a range of 0.4 to 30 S/m2 and the anodic oxidation film has a contact angle by pure water is restricted within a range of 30.degree. to 80.degree., thus improving the heat resistance of the aluminum substrate. The resulting photoconductor for electrophotography has an adequate degree of heat resistance and can give a good image characteristic even in a high-temperature and high-humidity environment.

Abstract: A new composition of titanyl phthalocyanine is provided. This composition has in its infrared absorption spectrum characteristically strong absorptions at absorption wavenumbers (in unit of cm.sup.-1) of 1490.+-.2, 1415.+-.2, 1332.+-.2, 1119.+-.2, 1072.+-.2, 1060.+-.2, 961.+-.2, 893.+-.2, 780.+-.2, 751.+-.2 and 730.+-.2, and has an extremely high solvent stability and dispersibility, and a large photoelectric conversion efficiency. The new form of composition can be obtained by adding to titanyl phthalocyanine, compounds of other phthalocyanines or naphthalocyanines as additives, and treating the amorphous composition of the mixture to crystallize the composition. By applying an appropriate binder, with the novel composition crystals as a charge generation agent, on a substrate, it is possible to obtain an electrophotographic photosensitive material that has a charge generation layer with an extremely high dispersibility and an extremely large photoelectric conversion efficiency.

Abstract: As a charge transport material for a charge transport layer of an electrophotographic photosensitive material, a poly-2,3-epoxypropyl carbazole compound is used together with a specific hydrazone compound and/or a specific butadiene compound. Film-formation property and adhesive property of the charge transport layer are much improved thereby to enable use of a photoconductive material in a higher concentration.
