Identified Intermediate Receptor Patents (Class 430/47.4)
  • Patent number: 8802336
    Abstract: An image forming apparatus may include an electrophotographic photoreceptor and an intermediate transfer member. An image may be formed by primary transferring a toner image held on a surface of an electrophotographic photoreceptor to an intermediate transfer member, and secondary transferring the toner image from the intermediate transfer member to a transferee material. A dispersive component of surface energy of the electrophotographic photoreceptor and a dispersive component of surface energy of the intermediate transfer member may satisfy a relationship of (the dispersive component of surface energy of the electrophotographic photoreceptor)?(the dispersive component of surface energy of the intermediate transfer member).

  • Patent number: 8712299
    Abstract: An image forming apparatus includes: a first image carrier; a first image forming unit that forms an image; an intermediate transfer belt; a primary transfer unit that primarily transfers the image onto the intermediate transfer belt; a secondary transfer unit that secondarily transfers the image transferred further onto a recording medium; a second image carrier that transfers the image onto the recording medium; a second image forming unit that forms an image on the second image carrier; a direct transfer unit that directly transfers the image onto the recording medium; a recording medium carriage belt, and a driving roller that drives the recording medium carriage belt; a speed fluctuation detecting unit; and a drive control unit that controls driving of the driving roller so as to reduce the cyclic speed fluctuation of the carriage belt based on a detection result of the speed fluctuation detecting unit.

  • Patent number: 8426090
    Abstract: It is an object to provide an intermediate transfer member that maintains a good second transferability and a good cleaning property even when print is repeatedly carried out and continuously obtains a high quality toner image without the occurrence of a non-printing portion of a character image, and an image forming method and a image forming device that use the intermediate transfer member. The intermediate transfer member is used for an image forming device provided with a means which, after the toner image carried on a surface of a photosensitive member is first transferred to the intermediate transfer member, the toner image is second transferred to a transfer member. The intermediate transfer member is characterized in that including an inorganic layer on the most outer surface, wherein the inorganic layer defines a contact angle of 30°-60° with respect to methylene iodide and the hardness of the inorganic layer measured by a nanoindentation method is in the range of 3 GPa-10 GPa.

  • Patent number: 7514190
    Abstract: An electrophotographic image forming method is disclosed, which includes the steps of developing an electrostatic image on a electrophotographic photoreceptor by a developer, transferring a toner image formed by the development, and fixing the toner image on a recording medium. It is disclosed that a toner has a volume particle diameter (Dv50) of about 4.4 to about 5.8 ?m and displays two or more endothermic peaks measured by DSC being within the rang of from about 50 to about 73° C. and the endothermic heat amount thereof is from 12.6 to 24.5 J/mg and a transferring member and/or a fixing member constituted by a belt containing a polyimide resin are employed in the method.

  • Publication number: 20070172748
    Abstract: The present invention provides a composite color image forming method. The method includes electrically charging a latent image-holding member; exposing the charged latent image-holding member to light to form an electrostatic latent image; developing the electrostatic latent image with a two-component developer containing toner particles of one color and a carrier to form a toner image on the latent image-holding member; primarily transferring the toner image from the latent image-holding member to an intermediate transfer member; repeating the electrically charging, the exposing, the developing, and the primarily transferring, while the toner particles are replaced with toner particles of different color, to form a composite color image on the intermediate transfer member; and secondarily transferring the composite color image from the intermediate transfer member to a recording medium.
