摘要： An image forming apparatus includes a photoreceptor belt formed by either a belt or a thin-walled cylinder. A charging unit that sets bias characteristics of the photoreceptor belt has an arrangement to approach towards the photoreceptor belt. A damper is provided on a side of the photoreceptor belt opposite to the side facing the charging unit. The damper absorbs vibrations in the photoreceptor belt through a supporting plate.

摘要： In an image forming apparatus, a revolver type developing device has a plurality of developing units and revolves to sequentially bring them to a developing position facing an image carrier on which a latent image is electrostatically formed. The revolver promotes easy replacement and safe handling of the developing units and can be accurately positioned relative to the body of the image forming apparatus. Despite that the revolver is miniature, it prevents developers from leaking or flying off from the developing units and contaminating the inside of the apparatus or being mixed with each other.

摘要： A developing device applicable to an electrophotographic copier, facsimile transceiver, laser printer or similar image forming apparatus and having a developing roller for carrying a nonmagnetic single component type developer, i.e., a toner and a toner supply roller for supplying the toner to the developing roller. The developing roller has dielectric portions and conductive portions each having a small area and distributed together on the surface thereof. The conductive portions are connected to ground and have a volume resistivity of 10.sup.6 .OMEGA.cm or below. The toner supply roller is made up of a metallic core and an elastic foam layer provided on the core and having conductivity and a predetermined frictional charging characteristic. A potential difference is set up between the developing roller and the toner supply roller to generate electric fields which act on a frictionally charged toner as a force directed from the toner supply roller toward the developing roller. Micropores existing in the surface of the toner supply roller have a depth and a size selected in such a manner as not to disturb microfields formed by frictional charges deposited on the dielectric portions. The two different kinds of electric fields exist together to enhance the supply of charged toner. To eliminate leaks between the two rollers, one of the rollers is semiconductive while the other roller is conductive, and use is made of a toner whose resistance is greater than predetermined one.

摘要： A latent image carrier includes a thin-walled cylinder with a chargeable photosensitive layer. The latent image carrier is configured to form an electrostatic latent image corresponding to an optically written image. A cylindrical damper including an elastic body disposed inside the latent image carrier. A first end of the cylindrical damper includes a wall extending inward toward an axis of the damper. A second end of the damper, opposite the first end along the axis of the damper, includes an opening, which is open in an axial direction. The wall includes a through-hole connecting an internal cavity and an outside of the damper. An outer diameter of an outermost part of the first end of the damper along the axis of the damper is smaller than an outer diameter of an outermost part of the second end of the damper along the axis of the damper.
