PROBLEM TO BE SOLVED: To provide a fixing device using an elastically deformable roller member, to obtain excellent fixing performance with a simple configuration.SOLUTION: A fixing device 20 comprises: a fixing member that heats and melts a toner image; and a pressure member which comes into contact with an outer peripheral surface of the fixing member to form a nip part with the fixing member. The fixing member is a fixing roller 21 having an elastically deformable core part 21a. The pressure member is a pressure roller 31 having higher rigidity than the core part 21a of the fixing roller 21, to fix a distance from a shaft center of the pressure roller 31 to the core part 21a of the fixing roller 21 farthest from the shaft center of the pressure roller 31. |
