Abstract

A contact fuser assembly 15 for use in an electrostatic repro-ducing apparatus including an internally heated metal core 31 cooperating with a resilient backup roll 33 to form a nip 34 through which substrates 35 carrying toner images 36 are moved with the toner images contacting the metal core. The fuser assembly is characterized by the provision of a sump 46 of liquid release agent material 48 which material is provided for coating the surface of the fuser roll structure. In order to apply the liquid release agent material to the surface of the fuser roll structure there is provided a cylindrical ap-plicator member 50 which is partially submersed in the release agent material. A ratchet wheel 60 and pawl 58 arrangement is provided for periodically indexing or moving the applicator member in response to disengagement of the backup roll from the fuser roll through pivoting of an arm 40 supporting the backup roll, To this end, the pawl member is pivotably sup-ported by the pivot arm and actuates the ratchet wheel each time the pivot arm is moved for effecting disengagement of the backup roll from the fuser roll.
