  • Toner release coating
    Patent number: 8304066
    Abstract: A toner release coating may be applied to a toner regulating member such as a doctor blade. The toner release coating may reduce toner adhesion at a doctoring pre-nip location of the doctor blade. The toner release coating may be formed from a mixture of lubricating particulate and polymeric binder resin in a liquid carrier.

  • Doctor blade surface energy modification
    Patent number: 8238803
    Abstract: The present disclosure relates to a surface energy reduction material in the form of a topcoat or additive to a coating that may be applied to a toner regulating member such as a doctor blade which may reduce toner build-up about a nip region, pre-nip region, and/or post-nip region. The surface energy reduction material may be include any material having a surface energy of less than or equal to 35 dynes/cm, for example, between 15-30 dynes/cm, including all values and ranges therein. The surface energy reducing materials may include any material that provides a 25% or more reduction of the surface energy of the doctor blade compared to an untreated doctor blade, for example, greater than or equal to 50% reduction or greater than or equal to 75% reduction, including all values and ranges therein.
