PROBLEM TO BE SOLVED: To provide a fixing device with which satisfactory fixing is made possible even under high-speed conditions by using a toner of a core-and-shell structure formed by coating the core surface composed of a crystalline resin with a non-crystalline resin, and an also to provide image forming apparatus equipped therewith. SOLUTION: In the fixing device of a roll and belt system for fixing the toner of the core-and-shell structure formed by coating the core surface composed of, for example, a crystalline resin with the non-crystalline resin, a pressing pad 16 as a first pressing section and a pressing rod 14 which is placed nearer the upstream side in the conveyance direction of a recording material P than the pressing pad 16 and presses a pressurizing belt 12 with the pressing force higher than that of the pressing pad 16 from the rear surface side to a pressing roll 18 in order to form a nip region of the roll belt. are placed. First, the surface layer (shell layer) composed of the non-crystalline resin of the toner is destroyed by the pressing force of the pressing rod 14 and thereafter, the heating and fixing are performed by the pressing force of the pressing pad 16.
