摘要： PURPOSE:To obtain good sensitivity over a wide wavelength range including the emission wavelength region of a semiconductor laser by using tau-type and/or eta- type metal-free phthalocyanine as an electrostatic charge generating material and a specified compd. as a charge transfer material. CONSTITUTION:A layer contg. a charge generating material and a layer contg. a charge transfer material are formed on a conductive substrate to obtain a composite type electrophotographic sensitive body. As the charge generating material, metal-free phthalocyanine of a type selected from tau-type, tau'-type, eta-type, and eta'-type is used, and as the charge transfer material, compds. represented by the formula, are used, in which X1-X3 are each aryl, and n is 0 or 1. Such a composite type photosensitive body is obtained, e.g., by forming a layer contg. the charge generating material on a conductive substrate and on this layer a layer contg. the charge transfer material or it may have a reverse constitution, or both materials may be contained in one layer. Ths use of a combination of such a charge generating and charge transfer materials enhances sensitivity even in a long wavelength region, and the obtained photosensitive body is especially suitable for a semiconductor laser printer using a semiconductor laser as a light source.

摘要： PURPOSE:To obtain an entitled photoreceptor superior in dimensional accuracy and suitable for a laser beam printer, by forming a photosensitive layer on a conductive substrate made of an age hardening type aluminum alloy. CONSTITUTION:An age hardening type aluminum alloy >=60Hv Vickers hardness, such as Al-(0.45-1.5)% Mg-(0.2-1.2)% Si alloy, is formed into a flate plate or a cylinder, subjected to age hardening heat treatment at 190-210 deg.C for 0.5- 1hr, the surface is precisely finished to a mirror, having a desired size, and washed to obtain a conductive substrate 1. On this substrate, a 40-100mum thick photosensitive layer 2 consisting of one or 2 layers selected from a selenium or its alloy layer, an org. compd. layer, a CdS layer, or a ZnO layer is formed by vapor deposition, and the substrate 1 is rapidly cooled at a >=5 deg.C/min speed, thus obtaining an electrophotographic receptor superior in finished precision, and resistance to mechanical damaging and impact.

摘要： PURPOSE:To increase the sensitivity over a wide wavelength range by combining a specified charge generating substance with a specified charge transferring substance. CONSTITUTION:In an electrophotographic receptor, a mixture or 1pt.wt. of copper phthalocyanine pigment with 0.1-10pts. oxazole deriv. represented by structural formula A is used as a charge generating substance, and trinitrofluorenone represented by structural formula B is used as a charge transferring substance. A layer of the charge generating substance having 0.5-5mum thickness and a layer of a charge transferring substance having 8-30mum thickness are laid on an electrically conductive support. Copper phthalocyanine has photosensitivity in the red region and said oxazole deriv. has photosensitivity in the blue region. When they are mixed, the photosensitivity in the red region is increased by about 1.5-2 times and the mixture has high sensitivity in 500-825nm, so it is suitable for a semiconductor laser light source.

摘要： PURPOSE:To reduce or prevent the generation of a stripe pattern due to light interference even when a photoconductor layer is exposed to interferential monochromatic light in a laser beam printer, by providing a light-absorptive layer on the substrate surface of a photosensitive drum. CONSTITUTION:In a laser beam printer, laser light interferes in a photoconductive layer because it is interferential monochromatic light to form a stripe pattern of light, which is superposed upon a charge latent image as well, so that a developed image has the stripe pattern. The generation of this interference stripe pattern is influenced most by reflected light on the surface of a substrate 9. On the surface of the substrate 9, a base layer 18 which absorbs light is provided to prevent light transmitted through a photoconductor layer 17 from being reflected by the surface of the substrate 9. For example, the base layer 19 is formed on the surface of the Al substrate 9 by a black ''Alumite '' treatement (formation of a surface film of aluminum oxide). The surface of the substrate 9 is coated with a mixture of carbon, coloring pigment, and dye with resin, or vapor-deposited with organic pigment metal.

摘要： PURPOSE:To provide the titled ink excellent in safety and rapid drying property and especially suitable for marking a food surface, a food package material or the like, containing an ethyl alcohol/water solvent, a dye, a binder and an ionizable salt comprising sodium benzoate or NH4Cl. CONSTITUTION:A solvent (A) comprising 95-70vol% ethyl alcohol and 5- 30vol% water, a dye (B) (e.g.; a xanthene dye such as erythrosine or floxin), an ionizable salt (C) comprising sodium benzoate or/and NH4Cl and a binder (D) (e.g.; a shellac resin) are compounded to prepare an ink for ink jet recording. The component C is pref. contained in an amount of 0.2-3wt% in the ink composition. EFFECT:Because said ink is composed of substances acceptable as a food additive, a coating with high safety and excellent water resistance is formed.
