Abstract
A fixing device includes: a flexible tubular member defining an axis extending in an axial direction; a first fixing member; a second fixing member configured to nip the tubular member in cooperation with the first fixing member; and a pair of restricting members disposed to interpose the tubular member therebetween in the axial direction. The tubular member has end faces in the axial direction and a circumference defining a circumferential direction. Each restricting member has a restricting surface abuttable with each end face of the tubular member to restrict the tubular member from moving in the axial direction, each restricting surface having a specific area continuously applied with a lubricant upon completion of assembly of the fixing device, the specific area having an arcuate shape extending in the circumferential direction and having a width at least equal to a thickness of the tubular member in the radial direction.
