Abstract
A fixing device may include an endless fixing belt, a facing member facing an outer surface of the fixing belt, a nip member configured to contact an inner surface of the fixing belt to form a nip portion where the fixing belt and the facing member are in contact with each other, and a heat source device configured to heat the nip portion inside the fixing belt. The nip member includes a heat transfer member which is provided at a position corresponding to a portion of the nip portion when seen from a side view, and a heat insulating member which is a portion of the nip member except for the heat transfer member, and is made of a material having thermal conductivity lower than that of the heat transfer member.
