Compliant doctor blade surface having molybdenum disulfide

Datetime:2016/7/1 16:18:44hit:10500


Compliant doctor blade surface having molybdenum disulfide. The conductive film (3) of a compliant doctor blade has dispersed particles of molybdenum disulfide, as well as dispersed particles of grit and conductive filler. The molybdenum disulfide eliminates filming of toner. The molybdenum disulfide may be a surface powder since the anti-film action occurs at the pre-nip and therefore is not lost by the molybdenum disulfide wearing away at the nip.


In accordance with this invention, the conductive film of a compliant doctor blade has dispersed particles of molybdenum disulfide, as well as dispersed particles of grit and conductive filler. The molybdenum disulfide naturally occurs in plate form and is used in that form in this invention, of average preferred particle size of 10 microns.


The molybdenum disulfide eliminates filming of toner. This is a function occurring at the pre-nip, since a powder coating of molybdenum disulfide has the same function even after it wears away within the nip.
