    摘要: A method of printing uses a liquid applicator to apply a coating solution containing polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer to an intermediate transfer medium. An image is printed onto the intermediate transfer medium using an ink jet printing device. The coating solution contains an organic solvent, which is preferably a glycol solvent or a diol solvent. Suitable solvents include trimethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, 1,2 butane diol, 2-pyrrolidone, gamma butyrolactone and glycerol. The coating solution is applied in an amount of 0.01 to 10 mg/cm 2 . The coating solution may contain 0.01 to 20 wt.% of polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer, 5-95 wt.% of an organic solvent and 5-95 wt.% water. More preferably, the coating solution contains 0.01 to 15 wt.% of polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer, 5-95 wt.% of an organic solvent and 5-95 wt.% water. Most preferably, the coating solution contains 2 to 8 wt.% of polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer, 5-95 wt.% of an organic solvent and 5-95 wt.% water. The PVP should have a molecular weight greater than 400,000, more preferably greater than 750,000 and most preferably within the range of from 850,000 to 1,500,000.

    摘要: 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 substantially squeegees 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 gases, and reduction in the operating potential between photoconductor drum and charging roller.

    摘要: A charging roller (42) and push plates (44) are spring mounted to the lid (36) of a printer. When the lid is closed, the plates push plungers (11) down to rotate crank arms (23), which open a shutter (7) in electrophotographic cartridge (1). This holds the cartridge in place and provides both a resilient, protective cushion for the cartridge and a pop-up action of the lid.
