    摘要： A transfer apparatus includes a transfer member, for example, a transfer drum with a line of small closely spaced laser drilled vacuum holes to hold a receiving sheet to the drum surface. The transfer drum is formed by forming a layer of at least intermediate conductivity material on the surface of a core, forming at least one vacuum opening in the core and laser drilling in the layer a line of closely spaced small holes communicating with the opening. In one embodiment, a short focal length lens focuses a laser beam near the surface of the layer, which beam spreads below the surface to form a conical hole. The conical hole helps maintain the continuity of a transfer field while being free from clogging.

    摘要： A transfer member, for example, a transfer drum utilizes a vacuum applied through vacuum holes to the drum surface for holding a receiving sheet. A toner image is transferred to the sheet under the urging of an electric field. To prevent non-transfer over the vacuum holes, the holes are filled or covered with a conductive material that is sufficiently conductive to maintain the electric field over the holes and sufficiently porous to maintain the vacuum at the surface. For example, a polyurethane foam material can be used for the material in or over the vacuum holes.

    摘要： A magnetic roller cleaning apparatus for removing residual toner particles from an image-bearing surface in a copier or printer includes a housing and a rotatable magnetic roller for moving a nap of a magnetic cleaning mix in the housing. The cleaning apparatus also includes a detoning roller for removing residual toner particles from the nap being moved by the magnetic roller. The cleaning apparatus further includes a magnetic member mounted externally on the housing and upstream of the detoning roller for mixing a top portion and a bottom portion of the nap on the magnetic roller prior to detoning.

    摘要： The present invention is used in an image-recording apparatus wherein a substantially uniform layer of triboelectrically charged thermoplastic toner particles is deposited onto an imaging member. The toner particles are imagewise heated such that the heated toner particles are thermally tacked to the imaging member. The imaging member is then contacted with a mass of magnetic carrier particles to attract nonheated toner particles to the carrier particles, thereby removing nonheated toner particles from the imaging member and ladening the carrier particles with the removed toner particles. In accordance with the invention, upon using the carrier particles to attract and remove toner from the imaging member, the toner-laden carrier particles are mixed with a supply of carrier particles in which the average number of toner particles per carrier particle is lower than that of said toner-laden carrier particles. This produces a mixture of carrier particles in which the average amount of toner attracted to each carrier particle is substantially lower than that of the toner-laden carrier particles. This mixture is then subjected to a detoning step in which essentially all of the toner on each carrier particle is removed prior to the carrier particles being contacted to the imaging member again.

    摘要： A development apparatus for developing latent images on an image-bearing surface includes a magnetic core generating a first magnetic field, a non-magnetic shell surrounding and spaced from the magnetic core, and a transport assist magnet mounted at a desired spot between the non-magnetic shell and the magnetic core. The transport assist magnet generates a second magnetic field at and about the desired spot thereby creating a magnetic field strength gradient thereabout for assisting the magnetic transportation of magnetic developer material over the surface of the non-magnetic shell.
