Abstract
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.
Claims10
A compliant blade for metering charged electrophotographic toner held on a developer roller by physically contacting a sector of said roller with an electrically conductive surface of said blade, said electrically conductive surface at least in the region prior to said contacting comprising molybdenum disulfide in plate form particles to reduce filming.
