| 20090035677 | CONDENSATION POLYMER PHOTOCONDUCTIVE ELEMENTS - The present invention relates to photoconductive elements having an electrically conductive support, an electrical barrier layer and, disposed over the conductive layer, a charge generation layer capable of generating positive charge carriers when exposed to actinic radiation. The electrical barrier layer, which restrains injection of positive charge carriers from the conductive support, comprises a crosslinkable condensation polymer having as a repeating unit a planar, electron-deficient, tetracarbonylbisimide group and optionally a crosslinker, | 02-05-2009 |
| 20090052964 | ELECTROSTATOGRAPHIC APPARATUS HAVING IMPROVED TRANSPORT MEMBER - The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member for producing an electrostatic latent image on a receiver, a development station for applying toner particles to said latent image which forms a developed toner image on the receiver. A fuser assembly is included for fixing the developed toner image, to form a fused toner image on the receiver. A transport member is provided for transporting the receiver to or from the fuser assembly, the transport member having a substrate bearing an oil-absorbing layer that includes transparent alumina inorganic particles of siloxane coated gamma-alumina, dispersed in an organic binder, and a fluorosurfactant. | 02-26-2009 |
| 20090105100 | FUSER FLUID - The present invention is a release oil of the general formulae: | 04-23-2009 |
| 20090136859 | SOL GEL OVERCOATS INCORPORATING ZINC ANTIMONATE NANOPARTICLES - The present invention is directed to an electrophotographic element that comprises: an electrically conducting layer, a charge generating layer overlying the electrically conducting layer, and a charge transport layer overlying the electrically conducting layer. The charge transport layer, which can be an overcoat overlying the charge generating layer, includes the reaction product in an aqueous medium of a mixture comprising a silsesquioxane polymer and a amine-free surface treated zinc antimonate and an acid scavenger. | 05-28-2009 |
| 20110103860 | ELECTROSTATOGRAPHIC APPARATUS HAVING IMPROVED TRANSPORT MEMBER - The present invention is an electrostatographic reproduction apparatus which includes a primary imaging member for producing an electrostatic latent image, a development station for applying toner particles to said latent image which forms a developed toner image, and a transfer station for transferring said developed toner image from the primary imaging member to a receiver. A fuser assembly is included for fixing the developed toner image to the receiver, to form a fused toner image on the receiver. An endless transport member is provided for transporting the receiver to or from the fuser assembly, the transport member having a substrate bearing an oil-absorbing porous layer that would tribocharge positively upon contact with negatively charged toner particles, and a porous overcoat outermost layer that does not tribocharge positively upon contact with negatively charged toner particles. | 05-05-2011 |
