Abstract
A fixing device includes a fixing rotator, a pressure rotator, a fixing nip support, a heat source, and a reflector. The pressure rotator contacts an outer face of the fixing rotator to form a nip through which a recording medium conveyed in a conveyance direction passes. The fixing nip support has a receiving portion to receive a pressing force of the pressure rotator. The heat source inside a loop of the fixing rotator has a heat generation area having a first length in a width direction orthogonal to the conveyance direction. The reflector includes a contacting portion contacting the receiving portion of the fixing nip support and a reflecting portion facing the heat source to reflect radiant heat radiated by the heat source toward an inner face of the fixing rotator. The reflecting portion has a second length in the width direction longer than the first length.
