  • Patent number: 5943542
    Abstract: A heat and pressure fuser and a Release Agent Management (RAM) system therefor. A dual function RAM system is provided. The dual function RAM system supplies functional release agent material having a relatively high concentration of functional chains (in the order of 0.05 to 0.4 mol %) to an elastomeric fuser member as well as release agent material having low funtionality or no functionality. The elastomeric fuser member may contain metal oxide particles. The low functionality release agent is relatively non-reactive. Depending on whether the elastomeric member contains the metal oxide particles, the functional chains of the high concentration release agent material which are periodically supplied to the fuser roll surface either attach to the metal particles exposed at the surface of the fuser roll by chemical bonds or to the elastomeric material itself. The non-reactive chains adhere to the functional chains by much weaker physical (such as van der Waals) chains.

  • Patent number: 5835833
    Abstract: A heat and pressure fuser and Release Agent Management (RAM) systems therefor. Dual RAM systems are provided. A first RAM system supplies functional release agent material having a relatively high concentration of functional chains (.about.O.05 to 0.3 mol %) to an elastomeric fuser member prior to a second RAM system which supplies release agent material having low functionally or no functionality. The elastomeric fuser member may contain metal oxide particles. The low functionality release agent is relatively non-reactive. Depending on whether the elastomeric member contains the metal oxide particles, the functional chains of the high concentration release agent material which are periodically supplied to the fuser roll surface either attach to the metal particles exposed at the surface of the fuser roll by chemical bonds or to the elastomeric material itself. The non-reactive chains adhere to the functional chains by much weaker physical (such as van der Waals) chains.

  • Patent number: 5734955
    Abstract: An apparatus for developing a latent image recorded on a surface, including a housing defining a chamber storing a supply of toner. A toner donor member is spaced from the image bearing surface and adapted to transport toner to a region opposed from the surface. A charging device is disposed in the chamber for ion charging the toner. An air injection system fluidizes the toner in the chamber. The injection system and a transport member cooperate with one another to define a region wherein a substantially constant quantity of toner having a substantially constant ion charge is deposited on the transport member. The toner is electrostatically transferred from the transport member to the donor member which contains interdigitated electrodes positioned near the surface of a dielectric core roll. An AC voltage is applied between the interdigitated electrodes to detach toner from the donor member so as to form a toner cloud for developing the latent image in an image on image process.

  • Patent number: 5557393
    Abstract: An electrostatographic imaging process includes forming an electrostatic latent image on an image forming device, developing the electrostatic latent image on the image forming device with at least one developer containing carrier particles and a blend of two or more compatible toner compositions, and transferring the toner image to a receiving substrate and fixing it thereto. Among the compatible toner compositions that may be selected are toner compositions having blend compatibility components coated on an external surface of the toner particles and particulate toner compositions containing therein blend compatibility components or passivated pigments. Electrostatographic imaging devices, including a tri-level imaging device and a hybrid scavengeless development imaging device, are also provided for carrying out the described process.
