Abstract
A liquid dispensing apparatus especially suitable for use in dispensing release oil in the fusing apparatus of a xerographic copier comprises a storage reservoir (101), a dispensing container (41) and an overflow tank (52). The storage reservoir (101) is arranged to deliver liquid to the dispensing container (41) on the application of heat, generated for example by operation of a fusing apparatus, to the storage reservoir. The dispensing container (41) includes an outlet through which liquid overflows into the overflow tank (52) when the liquid in the dispensing container reaches a predetermined level (53). Cooling of the liquid in the storage reservoir causes liquid to be drawn from the overflow tank back into the storage reservoir.
