Abstract
A fixing device includes a heating unit that is rotatable and includes a heat source; a pressing unit that is rotatable and forms a nip together with the heating unit; and a contact unit capable of coming into contact with and moving away from the heating unit. The contact unit is positioned so that the contact unit does not overlap a region above the heating unit in a vertical direction when the contact unit is in contact with the heating unit and also does not overlap the region above the heating unit in the vertical direction when the contact unit is separated from the heating unit.
Claims11
A fixing device comprising:
- a heating unit that is rotatable and includes a heat source;
- a temperature detector that detects a temperature of the heating unit;
- a pressing unit that is rotatable and forms a nip together with the heating unit;
- and
- a contact unit capable of coming into contact with and moving away from the heating unit,
- wherein the contact unit is positioned so that the contact unit does not overlap a region above the heating unit in a vertical direction when the contact unit is in contact with the heating unit and also does not overlap the region above the heating unit in the vertical direction when the contact unit is separated from the heating unit, and
- the temperature detector is positioned so that the temperature detector does not overlap a region above the contact unit in the vertical direction when the contact unit is in contact with the heating unit and also does not overlap the region above the contact unit in the vertical direction when the contact unit is separated from the heating unit.
A fixing device comprising:
- heating means that is rotatable and includes a heat source;
- a temperature detector that detects a temperature of the heating means;
- pressing means that is rotatable and forms a nip together with the heating means;
- and
- contact means capable of coming into contact with and moving away from the heating means,
- wherein the contact means is positioned so that the contact means does not overlap a region above the heating means in a vertical direction when the contact means is in contact with the heating means and also does not overlap the region above the heating means in the vertical direction when the contact means is separated from the heating means, and
- the temperature detector is positioned so that the temperature detector does not overlap a region above the contact means in the vertical direction when the contact means is in contact with the heating means and also does not overlap the region above the contact means in the vertical direction when the contact means is separated from the heating means.
