摘要： A fixing device includes a nip forming member disposed inside a fixing member and pressed against a pressing member via the fixing member to form a nip portion between the pressing member and the fixing member through which a recording medium bearing a toner image passes. A heat generator disposed inside the fixing member heats the fixing member outside the nip portion and has variable heat distribution over a width of the fixing member. A first temperature detector disposed inside the fixing member contacts an end portion of the heat generator in the width direction of the fixing member, opposite a surface facing the fixing member, to detect a temperature of the heat generator. A second temperature detector disposed inside the fixing member contacts a center of an inner circumferential surface of the fixing member in the width direction, to detect the temperature of the fixing member.
