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, and a secondary roller that co-operates with the developer roller. The developer roller is formed of a material having a specific resistivity of less than 1 x 106 Ω.cm. The secondary roller is formed of a material having a specific resistivity of 1 x 104 to 1 x 109 Ω.cm.
(FR) La présente invention concerne une unité de développement à encre électrophotographique liquide. L'unité comprend un rouleau développeur, et un rouleau secondaire qui coopère avec le rouleau développeur. Le rouleau développeur est constitué d'un matériau ayant une résistivité spécifique inférieure à 1 x 106 Ω.cm. Le rouleau secondaire est formé d'un matériau ayant une résistivité spécifique de 1 x 104 à 1 x 109 Ω.cm.
