Abstract
A release agent applicator for a copying machine in which voids in the release agent contained in the applicator are substantially eliminated, thus providing an improved spreading performance of the release agent onto a fixing roll of the copying machine. The release agent applicator is made of a porous polyethylene tetrafluoride tube, the pores of which are partially closed except in areas where the release agent is to ooze out onto the fixing roll. Those partially closed pores in the tube are partially closed by a flattening operation so that they cannot draw release agent thereinto by capillary action.
