Abstract
An electrophotographic device (1) in which a photoconductor drum (3) is charged by a charging roller (5). Insulating liquid (19, 30) is applied at their initial nip. The charging roller both charges and squeegees largely dry the photoconductor member. The liquid (19) may be produced by incomplete cleaning by a cleaning blade (21). Excess liquid is collected at the sides. This results in reduction in foreign gasses, and reduction in the operating potential between photoconductor drum and charging roller.
