    摘要： An image forming apparatus includes an image bearing member movable along an endless path; a helical gear, adjacent an end of the image bearing member, for transmitting a driving force to the image bearing member; a rotatable member contributable to image formation on the image bearing member and having a shaft urged toward the image bearing member; driving means for driving the shaft; and a coupler disposed between the driving means and the shaft of the rotatable member, and effective to transmit rotational force in a direction of the shaft substantially without transmitting force in a radial direction of the rotatable member.

    摘要： 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.

    摘要： The high carbon hot-rolled steel sheet contains, in terms of percentages of mass, 0.10 to 0.7% C, 2.0% or less Si, 0.20 to 2.0% Mn, 0.03% or less P, 0.03% or less S, 0.1% or less Sol.Al, 0.01% or less N, and the balance being Fe and inevitable impurities, and has a structure of ferrite having 6 μm or less average grain size and carbide having 0.10 μm or more and less than 1.2 μm of average grain size. The volume ratio of the carbide having 2.0 μm or more of grain size is 10% or less. The volume ratio of the ferrite containing no carbide is 5% or less. The manufacturing method thereof has the steps of hot-rolling, primary cooling, holding, coiling, acid washing, and annealing. The primary cooling step is to cool the hot-rolled steel sheet down to cooling termination temperatures ranging from 450° C. to 600° C. at cooling rates of higher than 120° C./sec. The holding step is to apply secondary cooling to hold the primarily cooled hot-rolled steel sheet at a temperature range from 450° C. to 650° C. until coiling.

    摘要： An image forming apparatus including an image bearing member and a rotatable member such as a transfer roller, a charging roller or a cleaning roller press-contacted to the image bearing member in relation to an image formation process on the image bearing member. A coupling is employed for transmitting the driving force from a driving power source to the rotatable member, so that the state of press-contact between the image bearing member and the rotatable member is maintained substantially uniform along the longitudinal direction with stability.
