Abstract
A fixing device includes a rotatable fixing member, a pressing member to contact the fixing member with pressure to form a nip between the pressing member and the fixing member, an induction heating unit serving as a heating source to heat the fixing member, and a conductive wire drawn out of the induction heating unit to be disposed outside the cover member through a hole provided substantially at a center of the cover member in a longitudinal direction of the induction heating unit. The induction heating unit includes an excitation coil, a coil holder to hold the excitation coil, and a cover member provided facing the coil holder with the coil holder interposed between the cover member and the fixing member.
