Zusammenfassung:A developing unit for a liquid electrophotographic printer such as a laser printer includes a cleaning means (170) for removing toner particles of the developer adhering to a surface of a squeegee roller (120) using an electrical force. In one embodiment the cleaning means comprises a cleaning roller (170) charged to about 1KV voltage difference with respect to the squeegee roller (120) to attract toner particles from the squeegee roller (120). Since the toner particles adhering to the squeegee roller are removed, contamination of a developed image can be prevented and a clean image can be printed.
