FIXING DEVICE HAVING FIXING BELT AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

Provided is a fixing device including a pair of end deformation restraint members. A restraint body 35 of the end deformation restraint member has an insertion part 38 which is inserted into both end portions of a fixing belt, and restrains deformation of belt end portions by holding both end portions of the fixing belt, which slides on an outer peripheral surface of the insertion part 38, from inside in the insertion part 38. The insertion part 38 is continued in a belt rotation direction with no gap.

主权项

1. A fixing device comprising:
a heating unit; an approximately cylindrical and flexible fixing belt heated by the heating unit; a pressing member that presses an inner peripheral surface of the fixing belt; and a pressure roller that is brought into press contact with the pressing member while interposing the fixing belt between the pressure roller and the pressing member and is rotationally driven in the press-contact state, thereby rotating the fixing belt, wherein the fixing device allows a paper to pass through between the fixing belt and the pressure roller to fix a toner image to the paper, the fixing device further comprising a pair of end deformation restraint members, wherein the pair of end deformation restraint members are configured to have insertion parts which are inserted into both end portions of the fixing belt and to restrain deformation of belt end portions by holding both end portions of the fixing belt, which slides on outer peripheral surfaces of the insertion parts, from inside in the insertion parts, and each insertion part is continued in a belt rotation direction with no gap.
