Title (EN) BINARY INK DEVELOPER (BID) ASSEMBLY FOR LIQUID ELECTROPHOTOGRAPHY (LEP) PRINTING DEVICE
(FR) ENSEMBLE DE DÉVELOPPEMENT D’ENCRE BINAIRE (BID) POUR DISPOSITIF D’IMPRESSION PAR ÉLECTROPHOTOGRAPHIE LIQUIDE (LEP)
Abstract:
(EN) A binary ink developer (BID) assembly for a liquid electrophotography (LEP) printing device can include a developer roller having an electrically insulating exterior coating that receives ink from an ink supply and transfers the received ink to a photoconductive imaging cylinder in accordance with an electrostatic image on the imaging cylinder. A charge-specified boundary condition can exist at the boundary between the exterior coating and the ink. Electrically conductive ink may not be transferred to the imaging cylinder at background portions of the electrostatic image.
(FR) La présente invention concerne un ensemble de développement d’encre binaire (BID) pour un dispositif d’impression par électrophotographie liquide (LEP) qui peut comprendre un rouleau de développement comportant un revêtement extérieur électriquement isolant qui reçoit de l’encre depouis une distribution d’encre et transfère l’encre reçue sur un cylindre d’imagerie photoconducteur conformément à une image électrostatique sur le cylindre d’imagerie. Une condition limite spécifiée par la charge peut exister au niveau de la limite entre le revêtement extérieur et l’encre. L’encre électriquement conductrice ne peut pas être transférée vers le cylindre d’imagerie au niveau de parties d’arrière-plan de l’image électrostatique.
