ABSTRACT:
An improved release agent applicator for use with a copying machine having a fixing device for pressure fusing a toner image to copy paper as the paper is passing between a fixing roll and a pressure roll. The fixing roll has in contact therewith a porous sheet or tube of poly(ethylene tetrafluoride) resin through which the release agent is applied to the fixing roll. The porous sheet or tube is installed on a support in such a manner that part of the sheet or tube projects from an opening of the support. The sheet or tube is provided with a backup which prevents the deformation of the sheet or tube. The backup is provided behind the sheet or tube and extends in the direction of rotation of the fixing roll.
