摘要： A developing device for developing an electrostatic latent image formed on an image bearing member such as a photosensitive member for use in an electrophotographic copying machine and the like using magnetic toner particles includes a rotatable sleeve, a magnet roll disposed inside of the sleeve and a doctor blade pressed against the sleeve for charging and forming a thin film of toner particles to be used in developing the latent image. In one form, the blade is provided movably in parallel with the rotating axis of the sleeve. In another form, an electrically conductive brush is provided to remove residual charges from the sleeve after each developing operation. In a further form, the tip end of the blade is disposed between the two adjacent magnetic poles of the magnet roll. In a still further form, the blade is constructed to have a two-part structure.

摘要： A curved pipe manufacturing method comprises the steps of: inserting a curved mandrel into a curved cavity of a fixed die having an entrance opening and an exit opening through the exit opening thereof, said cavity being formed in a circular arc and extending from the entrance opening to the exit opening thereof, said curved mandrel being attached to one side of a movable block; forming a curved pipe by pressing a work, with a presser rod through the entrance opening of the curved cavity into a curved space defined by the surface of the curved cavity and the mandrel; turning the movable block for extracting completely the curved pipe together with the mandrel from the exit opening of the curved cavity; inserting a retaining pin into a groove provided in the movable block for retaining a tip end of the curved pipe; and further turning the movable block so as to turn the mandrel while the curved pipe is restrained by the retaining pin so that the curved pipe is separated from the mandrel. An apparatus for carrying out the curved pipe manufacturing method is also provided.

摘要： A developing device includes a developing sleeve driven to rotate for transporting a film of charged developer as carried thereon past a developing station where the film of developer is applied to an electrostatic latent image to have it developed. Also provided is a sponge roller pressed against and driven to rotate in the same rotating direction as that of the developing sleeve, so that the developer is supplied to the developing sleeve at one side of the contact between the developing sleeve and the sponge roller and any residual developer on the developing sleeve is removed at the other side of the contact. Preferably, a desired voltage difference is established between the developing sleeve and the sponge roller. Furthermore, the sponge roller is preferably so structured to have a sufficient conductivity level at least at its outer peripheral surface thereby allowing the residual charge on the developing sleeve to be discharged sufficiently.

摘要： An electrostatic latent image developing apparatus supplies toner to a latent image carrier such as a drum-shaped photosensitive body to visualize a latent image formed thereon. The toner is supplied by a rotating drum-shaped toner carrier having a portion confronting the photosensitive body adjacent thereto and another portion held in contact with toner contained in a toner container. The toner is electrostatically attracted to the toner carrier and transferred therefrom to the photosensitive body. The toner on the toner carrier is regulated into a thin toner layer by a toner layer regulating member that is resiliently held in sliding contact with the toner carrier. To prevent toner deposits from being attached to the toner layer regulating member, the toner layer regulating member is made of a material adapted to wear with the attached toner. In order to provide the toner layer regulating member with an ability to triboelectrically charge toner, whether chargeable to a polarity (-) or (+), or to control the amount of electricity on toner chargeable to a polarity (-) or (+) and prevent toner deposits from being attached to the toner layer regulating member, another material to control the amount of electricity on toner is mixed in the material which can be worn with the attached toner.
