Abstract:
A fixing device includes an endless fixing belt, a heat source, an opposed member, a nip formation pad, and a heat conductive member. The nip formation pad includes an abutment region, a first opening portion, and second opening portions. The abutment region includes a plurality of abutment surfaces abutting a first face of the heat conductive member. The first opening portion is disposed at a center of the abutment region to form a non-contact area at which the nip formation pad does not contact the heat conductive member. The abutment region includes an upstream abutment area and a downstream abutment area from the first opening portion in a direction of conveyance of a recording medium. The second opening portions divide at least one area of the upstream abutment area and the downstream abutment area into a plurality of portions in a longitudinal direction of the nip formation pad.
