Yukiko Furushiro has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electrophotographic photoreceptor, process cartridge, and image forming apparatus
    Patent number: 8105739
    Abstract: An electrophotographic photoreceptor includes a conductive support and a photosensitive layer. The photosensitive layer is disposed on the conductive support, and includes a layer that includes, in the same layer, at least a charge generating material and a compound having a triple bond and a hydroxy group.
    Type: Grant
    Filed: March 24, 2008
    Date of Patent: January 31, 2012
    Assignee: Fuji Xerox Co., Ltd.
    Inventors: Wataru Yamada, Katsumi Nukada, Yukiko Furushiro
  • Image forming apparatus and process cartridge
    Patent number: 8055153
    Abstract: An image forming apparatus includes: an electrophotographic photoreceptor including a conductive support and a photosensitive layer including an outermost surface layer capable of transporting a charge, the layer being farthest from the conductive support and containing a resin having a crosslinking structure; a charging unit that charges the electrophotographic photoreceptor; a first exposure unit that exposes the electrophotographic photoreceptor to form an electrostatic latent image on the electrophotographic photoreceptor charged; a developing unit that develop the electrostatic latent image with a toner to form a toner image; a transfer unit that transfer the toner image from the electrophotographic photoreceptor to a medium to be transferred; and a second exposure unit that uniformly expose the electrophotographic photoreceptor, the outermost surface layer absorbing exposure light of the second exposure unit and having a maximum absorbance of about 0.
    Type: Grant
