Claims
- 1. A heat transfer station comprising:a transfuse member; an intermediate transfer member defining a transfer nip with said transfuse member, said intermediate transfer member having a pre-transfer nip region and a post-transfer nip region; a cooling platen contacting said intermediate transfer member at said post-transfer nip region and defining a fluid chamber for evaporation of a liquid; an evaporative liquid in said fluid chamber to cool said cooling platen; a heating platen contacting said intermediate transfer member at said pre-transfer nip region and defining a condensation chamber for condensing a gas to heat to said heating platen; and a gaseous passage to allow passage of an evaporated liquid from said cooling platen to said heating platen.
- 2. A method for transferring heat on a toner image bearing member comprising:contacting a cooling platen containing liquid to a heated image bearing member; evaporating said liquid to form a gas with said heat from said image bearing member; contacting a heating platen to said image bearing member; and condensing said gas on said heating platen to heat said image bearing member.
- 3. A method for heating and cooling a toner image bearing member defining a transfer nip with a transfuse member comprising:absorbing heat from a post-transfer nip region of the toner image bearing member to cool said toner image bearing member, wherein said absorbing heat from the post-transfer nip region of the toner image bearing member comprises evaporating a liquid; and transferring absorbed heat to a pre-nip region of the toner image bearing member to heat said toner image bearing member.
- 4. The method of claim 3 wherein said transferring absorbed heat to the pre-nip region of the toner image bearing member comprises condensing a gas to a liquid.
