摘要： Apparatus and methods for applying powder coatings to a substrate using a magnetic brush developer, including a method and apparatus for applying powder coatings to a substrate either directly or by intermediate transfer using a magnetic brush with a rotating magnetic field and for preparing the coating materials. The apparatus and method includes a supply of prepared powder coating material, a magnetic brush having a rotating magnetic field for applying the powder coating material to the substrate; and an electric field between the magnetic brush having a rotating magnetic field and the substrate.

摘要： 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.

摘要： An imaging system may use electrophotographic processes to synchronously image on both sides of a receiver material, such as in a single pass of the receiver material through the imaging system. The system may include intermediate transfer members, which may be split rollers or non-split rollers. The intermediate transfer members may hold one image, or they may be 2-up or greater rollers that hold multiple images.
