Title (EN) LIQUID ELECTROPHOTOGRAPHIC INK DEVELOPER UNIT
(FR) UNITÉ DE DÉVELOPPEMENT À ENCRE ÉLECTROPHOTOGRAPHIQUE LIQUIDE
Abstract:
(EN) The present disclosure relates to a liquid electrophotographic ink developer unit. The unit comprises a developer roller comprising a layer formed from a polymer composition containing a conductive filler, whereby the polymer composition has a specific resistivity of less than 1 x 106 Ω.cm. The unit also comprises a secondary roller that co-operates with the developer roller.
(FR) La présente invention concerne une unité de développement à encre électrophotographique liquide. L'unité comprend un rouleau développeur comprenant une couche formée d'une composition polymère contenant une charge conductrice, la composition polymère ayant une résistivité spécifique inférieure à 1 x 106 Ω.cm. L'unité comprend également un rouleau secondaire qui coopère avec le rouleau développeur.
