PROBLEM TO BE SOLVED: To provide a temperature control system for the roller (10) that is detachably mounted in an image forming apparatus. SOLUTION: The temperature control system comprises: a primary liquid circuit (20) formed in the roller and containing a first liquid; a secondary liquid circuit (24) formed outside of the roller and containing a second liquid; and a heat exchanger (22') arranged to bring the first and second liquid circuits into thermal contact with one another and comprising a first heat exchange member (30) that is in thermal contact with the first liquid circuit (20) and projects outwardly from the roller. The system is characterized in that the secondary liquid circuit (24) is defined inside of a stationary part (26) and is mechanically separated from the roller (10); the heat exchanger (22) comprises a second heat exchange member (32) arranged on the stationary part (26) to be in thermal contact with the second liquid circuit (24); and the first and second heat exchange means (30, 31) form heat transfer surfaces (34, 36) that are opposed to one another to permit heat transfer from one member to the other member.
