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 method and apparatus for producing an image on an imaging member. The apparatus includes a magnetic brush for depositing a substantially uniform layer of thermoplastic toner particles onto the imaging member. A laser scanner device is utilized to imagewise heat selected toner particles such that the selected toner particles are lightly tacked to the imaging member. The imaging member is contacted by a second magnetic brush, which includes a supply of magnetic carrier particles preferably having a coercivity of greater than about 100 oersteds, at least two times to remove nonselected toner particles from the imaging member. Alternatively, the imaging member may be contacted by two separate magnetic brushes at least one time to remove nonselected toner particles from the imaging member.

摘要： A uniform layer of charged toner particles is deposited onto a photoconductive layer of an imaging member. The toner particles are imagewise heated to imagewise tack selected ones of the particles to the photoconductive layer. The photoconductive layer is uniformly exposed to actinic radiation to discharge the toner particles while the layer is subjected to a gentle cleaning process which removes the nontacked toner particles.

摘要： Method and apparatus for producing a hardcopy reproduction of image information. A uniform layer of toner particles is applied to a surface. A receiver sheet with a thermoplastic outer layer is placed over the layer of toner particles, the thermoplastic layer contacting the layer of toner particles. An electrostatic attraction is established between the layer of toner particles and the receiver sheet. The thermoplastic layer is imagewise exposed to heat to selectively soften the thermoplastic layer, allowing the toner particles opposite the softened thermoplastic to migrate into the layer. The receiver sheet is then removed from the surface, taking with it the migrated particles in an imagewise pattern.

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.

摘要： Image forming apparatus includes a toner cleaning device for cleaning toner off an image surface. The cleaning device includes a cleaning applicator for moving magnetic particulate cleaning material past the surface to be cleaned. Particulate material is moved from a sump to the cleaning applicator by a transport positioned between them. A detoning roller is positioned to attract toner from particulate material associated with the transport. When the cleaning device is not cleaning, it has a mode of operation in which the transport and the detoning roller continue to operate to continue to detone particulate material which moves from the sump around the transport and back to the sump.
