In a digital printer comprising a developer station using liquid developer, the developer station has an application unit via which liquid developer is transported to a charge image carrier. The supply system adjacent and lateral to the application unit supplies liquid developer to the application unit. A pre-chamber and an electrode segment are provided, the pre-chamber being filled with liquid developer and open towards the application unit. The pre-chamber is open at a top such that a compensation volume of liquid developer with an open surface is created past which the application unit passes. The electrode segment is arranged adjacent to the pre-chamber and to a side of the application unit such that it forms a gap with the application unit through which the liquid developer is directed, the electrode segment being at an electrical potential such that toner of the liquid developer transfers to the application unit in the gap.
