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 xeroprinting master is formed by depositing a corona charge injection modifying material on a master substrate which includes a charge transport layer. The material can block the injection of charge that would otherwise inject into the charge transport layer or it can inject charge that would otherwise remain on the surface of the master. Preferably, the deposit is made by a conventional printer such as an ink jet, impact or thermal printer and the resulting deposit is not fused before use in xeroprinting.

摘要： A process for recording an erasable pattern which comprises selective deaggregation of an aggregate dye complex layer of a recording element. As a result, a color change occurs in the selected areas. In preferred embodiments, the pattern is produced by selectively exposing the layer to laser light. The pattern can be erased by exposing the layer to an appropriate solvent, or by heating the aggregate dye complex.

摘要： A magnetic brush development roller assembly for an electrographic printer includes a cylindrical multipole magnet mounted for rotation about a cylindrical axis; and a conductive non-magnetic stationary shell surrounding the multipole magnet. The shell defines an axial slot for receiving an imaging head, and has a region of reduced conductance extending substantially around the circumference of the shell, whereby eddy currents generated by rotation of the magnet within the shell and hence resistive heating and drag on the magnet are reduced.

摘要： Electrographic printing apparatus for forming a toner image on a recording medium, includes: a magnetic brush having a rotatable magnetic core and a stationary outer shell; a developer supply for supplying a magnetic developer powder including toner to the magnetic brush. A print head on the outer shell forms a plurality of parallel lines of developer. Toner is selectively transferred from a plurality of electrodes within each line to a receiver. A receiver electrode is arranged in spaced relation to the print head to define a recording region through which the receiver can be moved.

摘要： Electrographic printing apparatus for forming a toner image on a recording medium, includes a magnetic brush having a rotatable magnetic core and a stationary outer shell. A developer supply supplies a magnetic developer powder including toner to the magnetic brush. A print head is located on the outer shell of the magnetic brush. The print head includes microchannels or magnetic strips for forming a plurality of parallel lines of developer, and transfer electrodes for selectively transferring toner from two or more locations within each line to a receiver moving relative to the print head. The parallel lines of developer are arranged at an angle with respect to the direction of movement of the receiver, thereby effectively increasing the resolution of the print head in a direction perpendicular to the movement of the receiver. A receiver electrode is arranged in spaced relation to the transfer electrodes to define a recording region through which the receiver is moved.

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 ultraviolet radiation. As a result, exposed areas can be charged, while unexposed portions cannot. The photosensitive layer contains an organic photoconductor, an ultraviolet radiation sensitizer, and, optionally, an organic binder. A method of forming images with this photoelectrographic element is also disclosed.
