  • Patent number: 9017772
    Abstract: Various embodiments provide methods and apparatus for forming intermediate transfer belts (ITBs) by combining a dip-coating process with a UV-curing process. In an embodiment, an ITB substrate can be immersed into a liquid coating composition contained in a dip tank and then withdrawn from the liquid coating composition. When exiting the dip tank, the coated substrate can enter a UV-curing chamber for a UV-curing process. Multiple cycles of dip-coating and UV-curing can be performed such that a desired ITB substrate coating layer thickness can be obtained. After coating the ITB substrate, the UV-cured coating composition can be released from the ITB substrate, wherein the UV-cured coating composition released from the ITB substrate forms the intermediate transfer belt.

  • Patent number: 7829251
    Abstract: Disclosed herein is a flexible imaging member having a high concentration of a charge transport compound having optimum enhanced mechanical and electrical characteristics. By increasing the concentration of the charge transport compound to a level of from about 55 weight percent or more, including from about 55 weight percent to about 70 weight percent, and from about 55 weight percent to about 65 weight percent, a flexible imaging member can be produced with reduced residual voltage and/or improved sensitivity. Furthermore, the fatigue cracking resistance of the charge transport layer can be improved through the implementation of a heat stress release process described more particularly herein.
