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.
