PURPOSE:To improve the strength holding properties and releasing properties of two rotating bodies which clamp and carry a supporting material for an unfixed image, by forming said bodied of rotation of the 1st layer of fluororubber and the 2nd external layer of a mixture of fluororubber and fluororesin. CONSTITUTION:A heat roll 1 rotates as shown by an arrow 161, and a press roll 2 rotates in friction contact with the external circumferential surface of the roll 1 as shown by an arrow 162. The heat roll 1 has a fluororubber layer 3 of 50mum in thickness around the external circumferential surface of its metallic hollow roll core 11, and further has a mixture surface layer 4 of 25mum in thickness of fluororubber and fluororesin around said layer while incorporating a heater. The press roll 2 has a relatively thick silicone rubber layer 7 around its metallic roll core 6. When those two rolls 1 and 2 are brought into press contact by a known pressing means, both rolls 1 and 2 have a wide press-contacting area. |
