    摘要: A batchwise hot dip plating method is performed by dipping a metallic material in a molten metal plating bath, following fluxing by dipping the metallic material in a bath of a fused salt flux (e.g., a mixture of cryolite and one or more alkali metal chlorides and optionally aluminum fluoride) having a melting temperature at least 5.degree. C. higher than the temperature of the molten metal plating bath, which also serves to preheat the metallic material. In the case of hot dip plating with an Al--Zn alloy, particularly a Zn/55% Al/0.5-2% Si alloy, a bare spot-free plated coating having good appearance can be formed by a reduced duration of dipping in the plating bath without post-plating treatment to remove flux residues. The use of a plating tank having a cross section of a round shape such as a semicircular shape or an oblong semielliptic shape, rather than a rectangular box shape, brings about a significantly extended service life of the plating tank.

    摘要: In order to achieve such effects that memories such as image memory due to untransferred residual toner can be sufficiently prevented, and good images can be obtained by suppressing base fogging and reduction of entire image density for a long term, an oscillating voltage composed of a DC ingredient and an oscillating ingredient is applied to a charging device for charging a photosensitive member, while the charging device is in a position facing an image forming region of the photosensitive member. While the charging device is in a position facing an image non-forming region of the photosensitive member, only a DC voltage is applied to the charging device for at least a predetermined time.

    摘要: An image forming apparatus having an insulated member disposed adjacent to a photosensitive member, a scanner exposing an image on the photosensitive member in a direction perpendicular to the direction of movement of the insulated member while voltage is applied between the photosensitive member and the insulated member so as to provide a charge on the insulated member surface corresponding to the optical exposure image. The exposure position exposed by the scanner is changed in the direction of movement of the image-bearing member for each scan.
