摘要:
The carrier is used for a two-component developer for developing an electrostatic latent image, and includes a particulate magnetic core material; and a cover layer located on a surface of the particulate magnetic core material and including a crosslinked material. The crosslinked material is formed by hydrolyzing a copolymer including at least a unit (A) having a specific acrylic siloxane structure including a tris(trialkylsiloxy)silanyl group and a unit (B) having a specific acrylic silicone structure to form a material having a silanol group, and subjecting the material having a silanol group to a condensation reaction using an organic zirconium-containing catalyst.

摘要:
A rotatable pick roller and a rotatable separating roller are formed integrally with a roller case. A retard roller opposes the separating roller and rotates in a direction opposite to that of the separating roller. A lift detecting sensor is mounted on the roller case. When a first sheet and second sheet that are stapled together are accidentally placed on a sheet table, the pick roller picks-up the first sheet and feed it in the gap between the retard roller and the separating roller, the second sheet abuts with the retard roller so that a portion of the first sheet and the second sheet gets lifted. The lift detecting sensor detects the lifted portion and stops rotations of the rollers.
摘要:
A toner for forming a full color image, which includes a colorant and a binder resin including a polyester resin which is prepared by a polycondensation ester reaction in the presence of a titanium-containing catalyst selected from the group consisting of halogenated titanium, titanium diketone enolates, titanium carboxylates, titanyl carboxylates, and salts of titanyl carboxylates. A toner kit including a yellow toner, a magenta toner, a cyan toner and a black toner, wherein each of the toners is the toner mentioned above. An image forming apparatus including an image bearing member; a charger; a light irradiator; a developing device configured to develop an electrostatic latent image with a developer including the toner mentioned above; a transfer device; and a fixing device.
摘要:
The toner for developing a latent electrostatic image to form an image contains a binder resin and 2% by weight to 15% by weight of a coloring agent. The coverage of the toner with the coloring agent on a surface of the toner is 1.5% by atom to 15% by atom. The toner prevents scatterings and toner deposition on the background of images and provides high quality images even after printing several tens of sheets at high temperature and in high humidity.
摘要:
In implementing an induction heating stress improvement (IHSI) method in a nuclear plant, cooling characteristic with respect to the inner surface of piping is improved by appropriate structure/layout of nozzles, and further, the cooling effect when applying IHSI to a real machine is verified by installing a thermometer, as well as air in the portion subjected to IHSI is removed by heating the piping prior to the execution of IHSI.
摘要:
A backup system which can diminish a danger that backup data of a storage of a computer to be backed up sustains a damage due to disaster, an accident or the like, and restore the storage easily and within a short time when the storage up is damaged or lost due to disaster, an accident or the like. The system can be configured with a small facility investment. The system comprises a plurality of backup data storages, an archiving place determining unit for selectively determining a backup data storage physically away from an area in which the storage is located as an archiving place among the plural backup data storages on the basis of the area in which the storage is located, and a backup processing unit for storing the backup data in the backup data storage determined as the archiving place by the archiving place determining unit.
摘要:
An automatic paper feeder of a document input device includes a pick roller 20, separator pads 68 that come into contact with the pick roller 20, a first pair of pick springs 58, and a second pick spring 60. The first pick springs 58 are disposed on the upstream side of the second pick spring 60 in the direction of conveying the paper. The first pick springs 58 are disposed on the regions on both outer sides of the width of the separator pads 68 in the axial direction of the roller, and the second pick spring 60 is disposed at a central position in the width of the separator pad 68. The first and second pick springs 58 and 60 are integrally formed as a spring unit using a single metal plate, and a force of contact of the first pick springs 58 upon the pick roller 20 on the upstream side is smaller than a force of contact of the second pick spring 60 upon the pick roller 20 on the downstream side. The separator pad 68 is formed by branching a web 70 of a rubber sheet into fork-like pad units. The spring unit and the pad units are supported together by a bracket 76 and a holder member 78 (FIG. 6).
