  • Patent number: 6072976
    Abstract: Disclosed is an intermediate transfer member used for printing by an intermediate transfer method in an electrostatic recording process, which is capable of preventing adhesion and fusion of a tone on the surface of the intermediate transfer member as mush as possible, thereby obtaining a high quality image without dimming, positional offset and unevenness of color. The intermediate transfer member is disposed between an image forming body and a recording medium for allowing a toner image formed on the surface of the image forming body to be once transferred and held on the surface of the intermediate transfer member and to be then transferred on the recording medium. The intermediate transfer member includes a fabric layer having a structure of one or more layers; and an elastic layer laminated on either or each of surfaces of the fabric layer.
