Abstract
A fixing device includes a heating rotating member having a conductive layer and an exposed portion in which the conductive layer is partially exposed, and a roller including a metal core and an elastic portion, the roller forming a nip portion with the heating rotating member, the elastic portion being elastically deformed in a region where the nip portion is formed, wherein an annular conductive member provided in a longitudinal end portion of the metal core is in contact with the exposed portion of the heating rotating member while elastically deformed, and wherein in a state where the roller is not mounted to the fixing device, an outer diameter of the conductive member is smaller than an outer diameter of the elastic portion.
