摘要:
An electrophotographic photosensitive member capable of outputting an image in which a defect such as a ghost is suppressed even in a high-temperature-and-high-humidity environment, and in which a defect such as a change in density due to an abrupt change in light-area potential at an initial stage or a ghost due to long-term durable use is suppressed even in a low-humidity environment; and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member; are provided. The electrophotographic photosensitive member has a layer which comprises a compound having a specific structure between a support and a charge-generating layer.

An electrophotographic apparatus has a beam spot made to have a small spot diameter by the use of a laser having an oscillation wavelength within the range of from 380 nm to 450 nm, and enables image reproduction at ultra-high resolution and with ultra-high image quality. The apparatus includes I) an electrophotographic photosensitive member unit having i) an electrophotographic photosensitive member having a photosensitive layer on a cylindrical support and ii) fitting members fitted to the end portions of the electrophotographic photosensitive member, and II) an exposure device having a laser having an oscillation wavelength within the range of from 380 nm to 450 nm, and in which a spot diameter Di (μm) of a beam spot formed on the surface of the electrophotographic photosensitive member by a laser beam emitted from the laser is 40 μm or less, and the cylinder deflection De (μm) of the electrophotographic photosensitive member unit is 1.5 times or less the spot diameter Di (μm) of the beam spot.
摘要:
Pure water dissolving nitrogen gas and containing microbubbles is supplied to a substrate. Since microbubbles are very minute in size and also have the electrostatic property, they can efficiently adsorb particles on the substrate surface or in the pure water. Further, since pure water dissolving nitrogen gas is unlikely to be charged, the pure water itself never carries new particles from each component of the apparatus. These functions allow efficient particle removal from the substrate surface or the liquid.

A pelvis correction apparatus is disclosed, by which appropriate pelvis correction therapy is performed with application of sufficient pressing force at a predetermined angle to a patient by simple operation irrespective of therapist's skill. The apparatus includes a bed, pressing bars which moves from both sides of the bed toward a pelvis of the patient on the bed with a predetermined inclination angle, the pressing bars having pressing members on one ends, the pressing members brought into contact with the patient to convey pressing force to the pelvis, and a member for urging the movement of the pressing bars.

The disposable tooth cleaning article for manually cleaning tooth surfaces is disclosed. The disposable tooth cleaning article extends in a longitudinal direction and a transverse direction, and has a wearer's finger faced surface and an outer surface. The disposable tooth cleaning article comprises a first sheet and a second sheet. The first sheet and the second sheet form a pouch with an opening. The disposable tooth cleaning article has a distal portion extending opposite to the pouch beyond the opening in the longitudinal direction. The distal portion is wound about the wearer's finger when the disposable tooth cleaning article is used. The finger faced surface is provided with a first attachment means and a second attachment means. The first attachment means is located on the finger faced surface of the distal portion adjacent to one transverse edge of the opening to maintain the wound configuration of the distal portion. The second attachment means is located on the finger faced surface of the disposable tooth cleaning article to contact to the wearer's finger when the distal portion is wound about the finger.
