    摘要： A toner layer regulating system for an electrophotographic image forming apparatus includes a toner carrier; a toner regulating member supported in cantilevered fashion against the toner carrier so as to form a toner nip therebetween comprising a flexible metallic substrate having a coating covering at least an area forming the nip; wherein the coating comprises at least a matrix of a base polymer and a plurality of fine particles having a particle size of 0.1 microns to thirty microns; wherein the coating has a thickness of approximately one hundred fifty microns or less; wherein the coating has a surface roughness in the range of 0.15 to 1.5 microns Ra and in the range of 1 to 15 microns Rz. A carrier stratum may be disposed between the coating and the substrate, and the coating may be single layer or have a plurality of layers.

    摘要： A method of printing uses a liquid applicator to apply a coating solution ontaining 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, di propylene glycol, tri propylene 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/cm2. 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.
