摘要： A bleachable composition, including an acid photogenerator and a near-infrared radiation-absorbing dye or pigment, is utilized in a method of migration imaging to prevent unwanted absorptions. This composition can be incorporated either in the thermoplastic imaging surface layer of the imaging element, in the marking particles applied to the element, or both. Alternatively, the components of the bleachable composition can be separated with one in the thermoplastic imaging surface layer and the other in the marking particles. After the imaging element is marked and exposed with near-infrared radiation, the bleachable composition caused exposed portions of the imaging element to be bleached. If further bleaching is needed, the element can subsequently be exposed with near-ultraviolet radiation. A migration imaging method, which does not employ the bleachable composition of the present invention, wherein marking particles are magnetically attracted to the imaging element, is also provided.

摘要： A xeroprinting master includes a fixed insulative toner image on an electrophotographic element of the type exhibiting charge injection at an interface between a charge injection electrode and a charge transport layer. In xeroprinting use the master is charged to a polarity opposite that which is injectable. The charge is neutralized by charges injected from the electrode which migrate to the charged surface. Charge retained on the fixed toner image can be toned. The master can be made by positively charging it to a polarity the same as that which is injectable, imagewise exposing it and toning and fixing.

摘要： A migration imaging system using a laser-addressable thermoplastic imaging member. The imaging member comprises a supporting section and a thermoplastic imaging surface layer. A charged, uniform layer of marking particles is deposited on the imaging surface layer. An imagewise-modulated laser beam transforms selected volumes of the imaging surface layer in an imagewise pattern to a permeable state. Charged marking particles that superpose a transformed volume then migrate into the imaging surface layer so as to be retained. Unaddressed marking particles are cleaned away. The imaging member, or solely the imaging surface layer, may be transferred and bonded to a receiver such as a drum for use as an exposure mask, or to a receiver sheet to provide a hard copy reproduction. The processed imaging member is usable as a master in a xeroprinting system.

摘要： A migration imaging system using a laser-addressable thermoplastic imaging member 10. The imaging member 10 comprises a supporting section 15 and a thermoplastic imaging surface layer 14. A charged, uniform layer of marking particles 24 is deposited on the imaging surface layer 14. An imagewise-modulated laser beam 24 transforms selected volumes of the imaging surface layer 14 in an imagewise pattern to a permeable state. Charged marking particles 42 that overlay a transformed volume then migrate into the imaging surface layer 14, due to an electrostatic attraction to the imaging member 10, so as to be retained. Unaddressed marking particles 56 are cleaned away by particle removing device 20B comprised of a magnetic brush utilizing hard magnetic carrier particles. The imaging member 10, or solely the imaging surface layer 14, may be transferred and bonded to a receiver member such as a drum for use as an exposure mask in a xeroprinting process, or to a receiver sheet 64 to provide a hard copy reproduction. This migration imaging system provides an inexpensive method and apparatus for imaging which generates relatively little waste products.

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 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 photoelectrographic element for electrostatic imaging, containing a conductive layer and a photosensitive layer, is produced using photosensitive layer materials which form a barrier to charge injection where exposed to near-infrared radiation. As a result, exposed areas can be charged, while unexposed portions cannot. The photosensitive layer contains an organic photoconductor, a near-infrared radiation sensitizer, and, optionally, an organic binder. A method of forming images with this phctoelectrographic element is also disclosed.

摘要： Method and apparatus for the production of a hard copy reproduction of image information. After imagewise exposure of one or more uniform depositions of marking particles in one or more respective image frames on a web, the image frames are cleaned by a novel magnetic brush cleaning apparatus which provides a differential cleaning action, whereby the unexposed marking particles are removed while the exposed marking particles are left in place. The resulting transferable images are then transferred from the image frames to a one or more receivers. After transfer, each receiver is transported to a fuser where the transferred image is fixed.
