  • Publication number: 20080035265
    Abstract: The present invention is a process for making an intermediate transfer member. The process includes forming an endless belt by seaming two ends of a substrate material to form a seam. A smoothing layer is applied on top of the endless belt using a rotary cast process wherein said intermediate transfer member has a continuous seamless top surface. In a preferred embodiment the endless belt is formed by adhering at least two layers of a substrate to form a belt having an inner and outer seam.

  • Patent number: 5006897
    Abstract: In electrostatographic apparatus, the ratio of toner particle electrostatic charge-to-toner particle mass and the development rate are determined by providing a piezo device positioned to interact with toner particles. The device is periodically electrically biased to attract toner particles, and the frequency shift of the piezo device due to the mass of attracted toner particles is detected. The electrostatic charge buildup on the electrode due to the attracted toner particles is detected to determine the mass of toner. The potential on the device may be changed periodically from a potential which attracts toner to a potential which repels toner to clean the device.
