发明名称 FIXING DEVICE AND IMAGE FORMING APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide a fixing device and image forming apparatus for stably butting a planar heating element on a fixing member at a low pressure and uniformly heating the fixing member while it is rotated at a low torque.SOLUTION: The fixing device includes a fixing sleeve 21, a pressure roller 31, an abutting member 26 that is arranged on the inner peripheral side of the fixing sleeve 21 and abuts on the pressure roller 31 via the fixing sleeve 21 to form a nip section, and a planar heating element 22 as an elastic sheet that is arranged on the inner peripheral side of the fixing sleeve 21, comes into contact with the fixing sleeve 21, and heats it. The main surface of the planar heating element 22 is in contact with the inner peripheral surface of the fixing sleeve 21 at a surface pressure applied by bending elastic force of the planar heating element 22.
