    摘要： The developing device includes a developer bearer, a conveyor, a casing including a ceiling, and a seal. The developer bearer is configured to bear a developer and develop a latent image. The conveyor is configured to convey and stir the developer. The casing is configured to contain the developer, the developer bearer, and the conveyor. The seal is configured to seal the inside of the casing to form a closed space that encloses the developer in the developing device. The conveyor is configured to be partially or entirely buried in the developer enclosed in the closed space in both of a normal posture and an upside-down posture of the developing device. A cross-sectional area of the closed space in a horizontal plane gradually increases from a top of the ceiling of the casing toward a bottom of the developing device in the normal posture of the developing device.

    摘要： Cleaning brush is provided in the down stream of the cleaning member around the pressing member, and after toner stuck to the pressing member is recovered by the cleaning member, calcium carbonate stuck to the pressing member is recovered by the cleaning brush. Thus the toner volume stuck to the surface of cleaning brush is reduced and the calcium carbonate recovery performance by the cleaning brush is maintained.

    摘要： Unnecessary leakage current to a semiconductor substrate is prevented when a forward current flows through a diode. An N-type well region is formed in a surface of a P-type semiconductor substrate. A P-type well region is formed in the N-type well region. An N+-type diffusion layer is formed in a surface of the N-type well region outside the P-type well region. A P+-type diffusion layer and an N+-type diffusion layer are formed in a surface of the P-type well region. The N+-type diffusion layer formed in the surface of the N-type well region is electrically connected with the P+-type diffusion layer formed in the surface of the P-type well region with a wiring made of aluminum, for example. An anode electrode is connected with the wiring. Also, a cathode electrode is connected with the N+-type diffusion layer.

    摘要： Wear resistant member for electronic equipment comprises a silicon nitride sintered body that contains conductivity enhancing particles, and has electrical resistivity in the range from 1 to 105 &OHgr;·m. In silicon nitride sintered body, agglomeration of conductivity enhancing particles in which distance between conductivity enhancing particles is less than 1 &mgr;m exists by 30% or less by area ratio per unit area. Wear resistant member is used for a bearing ball or the like, being applied in a rotation actuator of electronic equipment such as a magnetic recorder and optical disk drive. Malfunction of electronic equipment due to static electricity may be cancelled due to electrical resistivity that silicon nitride sintered body has.

    摘要： A developing device includes a developer bearer, a magnetic field generator provided inside the developer bearer, a casing including an opening to partly expose a surface of the developer bearer, and a lateral end cover to cover an axial end portion of the exposed surface of the developer bearer. The lateral end cover includes a wide portion extending more to an axial inner side of the developer bearer than a downstream portion of the lateral end cover positioned downstream from the wide portion in a direction of rotation of the developer bearer. A downstream end of the wide portion is downstream from an upstream end of the development range in the direction of rotation of the developer bearer.
