  • Intermediate transfer member of thermoplastic film forming polymer layer laminated onto a base layer
    Patent number: 5525446
    Abstract: An intermediate transfer member includes a base layer and a top thermoplastic film forming polymer layer. The base layer can include carbon and the thermoplastic film forming polymer layer can include electrical property regulating materials. This intermediate transfer member shows improved mechanical as well as electrical properties. It can be employed in an electrophotographic imaging device having at least one photoreceptor and can print an image on a suitable substrate such as paper with improved toner image formation.

  • Method of manufacturing a reinforced seamless intermediate transfer member
    Patent number: 5409557
    Abstract: A seamless intermediate transfer member has a reinforcing member in an endless configuration, a filler material such as a polymer and electrical property regulating material to regulate the electrical properties such as surface and bulk resistivity, dielectric constant and charge dissipation. The seamless intermediate transfer member also has good mechanical properties. The reinforcing member can be prepared by any suitable method such as by weaving. Filler material and electrical regulating material can be applied on, around or embedded into the reinforcing member. The member can be employed in an electrostatographic imaging system with more than one toner imaging station. The member can pick up a separate image from each individual imaging station and transfer the combined image to a suitable substrate.
