Abstract
An improved release agent applicator for use with a copying machine in which a porous polyethylene tetrafluoride resin tube is installed in a support with the part of the tube which forms an outlet for the release agent contained in the tube projecting from an opening in the support. The outer surface of the porous tube is covered with a film of a polymer having a low melting point, such as polyethylene. When the applicator is installed, the normal heating of the fixing roll causes the polymer film to melt, opening the applicator for use. Accordingly, leakage from the applicator prior to use is prevented.
