  • Patent number: 10248056
    Abstract: A fixing device includes a fixing member, a pressuring member and a temperature sensing part.

Detection temperature of the fixing member is calculated with a sensing value by the infrared sensing element. The detection temperature or control temperature of the heat source is corrected with temperature deference between the infrared sensing element and the condensing member. Heating of the fixing member is controlled with the corrected detection temperature and the control temperature or the detection temperature and the corrected control temperature.

The retaining member has the charge elimination member fixed thereto. The contact sheet metal is held at a specified potential. The first contact member electrically connects the charge elimination member and the contact sheet metal to each other. The retaining member has a hollow cylindrical-shaped positioning boss, and the fixing housing has an insertion hole into which the positioning boss is to be inserted. The first contact member is placed inside the positioning boss and has one end protruded from the positioning boss. The contact sheet metal is placed so as to face the positioning boss.
