Abstract
A transfer assist blade for an electrophotograhic printing machine that provides the necessary stiffness to allow complete transfer of a toner image while avoiding excessive bending stress in the blade. The blade is made up of a semiconductive polyester layer bonded to a non-semiconductive polyester layer. A third and fourth layer of high molecular weight polyethylene are bonded o the second layer. These third and fourth layers do not extend the full length of the blade to provide supplemental stiffness while avoiding excess bending stress.
Claims8
A composite transfer assist blade, comprising a plurality of layers wherein at least one of said plurality of layers comprises a polyester material having a semiconductive coating thereon, a second one of said plurality of layers comprising a second polyester material bonded to said first polyester layer and a third one of said plurality of layers comprising a high molecular weight polyethylene material bonded to said second polyester material.
An electrophotographic printing machine having a photoreceptive member and including a composite transfer assist blade, comprising a plurality of layers wherein at least one of said plurality of layers comprises a polyester material having a semiconductive coating thereon, a second one of said plurality of layers comprising a second polyester material bonded to said first polyester layer and a third one of said plurality of layers comprising a high molecular weight polyethylene material bonded to said second polyester material.
