Apparatus for supplying silicone oil or other suitable release agents to a heated f user roll is disclosed, A wick structure 10 comprising a supply wick 12 and a cover wick 14 is adapted to contact a heated fuser roll to thereby apply silicone oil 15 or the like to the surface of the roll. The silicone oil is contained in a sump 16 and it is conveyed to the supply wick 12 via a tube 18 extending from the bottom of the sump to the supply wick. A reservoir 20 holds a quantity of oil for automatically replenishing oil depleted from the sump. To this end, a valve 22 providing communication between the sump and reservoir is actuated by a float structure 24 to allow passage of oil from the reservoir into the sump when the level of oil in the sump falls below a predetermined level.
