There is provided an image forming apparatus that can suppress the formation of creases when forming images on both surfaces of a sheet and can greatly reduce the incidence of unprinted areas. The image forming apparatus has a sheet stacking section in which sheets are stacked, a sheet conveying section that conveys a sheet, an image forming section that forms an image on the sheet while the sheet is conveyed, a re-conveying section that again conveys the sheet with the image formed on a first surface thereof to the image forming section, and a sheet feeding section that feeds a sheet from the sheet stacking section or the re-conveying section to the image forming section. When a sheet is fed from the sheet stacking section for image formation on the first surface of the sheet by the image forming section, the sheet is fed at a first speed, and when a sheet is fed from the re-conveying section for image formation on a second surface of the sheet by the image forming section, the sheet is fed at a second speed that is slower than the first speed and is slower than the speed at which the sheet is conveyed by the sheet conveying section.

A recording material detecting apparatus includes a detecting device and a reference member. The detecting device irradiates a recording material with light and detects the light from the recording material. The reference member has a reference portion detectable by the detecting device in order to correct the output from the detecting device. The reference member is capable of moving from a position where the reference portion is detected by the detecting device. The reference member is moved by the recording material. Since a driving unit such as a motor is not necessary, the cost of the apparatus body can be dramatically reduced, and the apparatus structure can be dramatically simplified.
摘要:
To provide a system by which evaluation of circumstances of contamination by microparticles having nucleic acid can be performed rapidly and accurately. The theme is achieved by a system for measuring microparticles that includes: (1) a microparticle adhesion step of adhering the microparticles having nucleic acid to a microparticle adhesion member; (2) a membrane breakage step of breaking membranes of the adhered microparticles by electrical discharge; (3) an electrophoresis step of electrophoresing the microparticles in a thickness direction of a gel to make the nucleic acid in the microparticles migrate from a negative electrode side toward a positive electrode side and adhere the nucleic acid on a surface of a nucleic acid detection member; and (4) a nucleic acid measurement step of fluorescently staining the surface of the nucleic acid detection member to measure a concentration of the nucleic acid.
