PROBLEM TO BE SOLVED: To provide a fixing device capable of enhancing the portability of a transfer material. SOLUTION: In this fixing device, a fixing roller 1 and a pressure roller 4 having an elastic layer whose thickness is about 1mm to 3mm on a cylindrical core bar are rotated while abutting on with linear pressure >= about 0.8kg/cm and interpose and carry the transfer material P, and a toner image on the transfer material is melted and fixed on the transfer material by heating the roller 1 or 4. The elastic layer thickness and the circumferential speed of the roller 1 and 4 are set to satisfy t1 <t2 , and v1 >v2 , assuming that the elastic layer thickness and the circumferntial speed of either the roller 1 or 4 are t1 and v1 , and the elastic layer thickness and the circumferential speed of the other are t1 . and v2 . |
