Abstract
A fixing device includes a rotatable endless belt, a pressure rotator, a heating rotator, a pad, an intermediate member, and a holder. The pad is disposed inside a loop of the endless belt and pressed by the pressure rotator to form a fixing nip portion between the endless belt and the pressure rotator. The intermediate member has a pad abutment portion to abut on the pad at a fixing nip facing portion of the pad. The holder holds the pad and the intermediate member, and has an intermediate member abutment portion to abut on a pad facing portion of the intermediate member. The pad has a recess in the fixing nip facing portion. The pad abutment portion abuts on the fixing nip facing portion and covers the recess in at least a part of the fixing nip portion corresponding to a passage region of a recording medium.
