PROBLEM TO BE SOLVED: To provide a temperature control unit for a cylindrical substrate which is capable of simply and more uniformly suppressing or controlling a temperature rise of the whole cylindrical substrate in irradiation with ultraviolet rays and to provide a manufacturing method. SOLUTION: The temperature control unit for an electrophotographic photoconductor substrate having the cylindrical substrate having a coating layer, a heat generating body irradiating the cylindrical substrate with energy from the outside, and a rotation means which rotates the cylindrical substrate, to irradiate the entire circumference with the irradiation energy of the heat generating body contains a stretchable membrane member which is disposed in a hollow space of the cylindrical substrate, wherein the membrane member is configured to sequentially stretch until reaching a chucking portion attached to the cylindrical substrate, as a result of an introduction of a refrigerant therein to closely contact with an entire inner wall of the cylindrical substrate, and to sequentially shrink to the original shape thereof as a result of a release of the refrigerant therefrom, so that a heat transfer is made between a surface of the cylindrical substrate and the refrigerant introduced in the hollow space of the cylindrical substrate via the membrane member in a closely contact state, to control a surface temperature of the cylindrical substrate.
