摘要:
An embodiment of a screw conveyor includes a rotating shaft and a conveying blade helically formed around and loosely coupled with the rotating shaft. One or both of two edges of the conveying blade is/are only fixed to the rotating shaft, and a gap is provided between the rotating shaft and the conveying blade. Thereby, the conveying blade can be vibrated in a center axis direction of the rotating shaft by rotation of the rotating shaft and conveyed waste developer.
摘要:
A first control member is disposed in a drum shaft away from a photoconductive drum, and a second control member is disposed in a roller shaft away from a transfer roller. The first and second control members abut on each other at their circumferential surfaces. This helps reduce an amount of displacement resulting from an impact caused by insertion of a recording paper sheet in between the photoconductive drum and the transfer roller, and thereby reduce vibrations in the photoconductive drum. Consequently, a toner image formed on the photoconductive drum and an unfixed toner image transferred onto the recording paper sheet are not affected by vibrations, so that a high-quality image is obtained that is free from blurriness or irregularities.

An object of the invention is to convey a transfer material properly and securely in a simple structure even where space allowance is limited. An image forming apparatus has a photoconductive body and a transfer device composed of a transfer roller. After a developer image formed on the photoconductive body is electrostatically transferred onto a sheet by the transfer roller, a rear end of the sheet having passed through opposed regions of the transfer roller and the photoconductive body is, by a guiding roller arranged at a downstream side of the opposed portions along a sheet conveying path, guided in conveyance from a non-transferred surface of the transfer material so that it is kept out of contact with the transfer roller.

The present invention is made to provide a pretransfer charging device, which allows (i) reduction of generation of discharge products such as ozone and nitroxide, (ii) excellent uniform charging, (iii) continuous stable charging for a long period of time, and (iv) restraint of distortion of a toner image. The pretransfer charging device includes (i) ion generation needles each provided face to face with an image carrier such as a photoconductor drum or an intermediating transfer belt, and (ii) a high-voltage power supply for applying a negative voltage to each of the ion generation needles. The voltage to be applied from the high-voltage power supply is not less than an ion production threshold voltage but is less than a corona discharge threshold voltage. With this, no corona discharge occurs but negative ions can be generated. This makes it possible to solve various problems caused due to the corona discharge.

摘要:
A method of immunoassay of H5 subtype influenza A virus by which the virus can be accurately assayed even in cases where a certain level of mutation has occurred in the H5 subtype influenza A virus, and a kit therefor, and a novel anti-H5 subtype influenza A virus monoclonal antibody which can be used for the immunoassay are disclosed. The antibody or an antigen-binding fragment thereof of the present invention undergoes antigen-antibody reaction with hemagglutinin of H5 subtype influenza A virus, and the corresponding epitope of the antibody or an antigen-binding fragment thereof is located in a region other than the receptor subdomain (excluding C-terminal region thereof consisting of 11 amino acids), which antibody or an antigen-binding fragment thereof does not have neutralizing activity against the influenza A virus.

Provided are a highly-safe recombinant vaccinia virus that is effective in preventing the onset of symptoms due to infection by novel influenza viruses, and a vaccine for the novel influenza viruses containing the recombinant vaccinia virus. This recombinant vaccinia virus is capable of expressing the hemagglutinin protein genes of the novel influenza virus. This novel influenza vaccine contains the recombinant vaccinia virus.
