Abstract
A fixing device includes a heating element extending in a first direction and configured to generate heat, a nip member extending along the heating element in the first direction and configured to receive radiant heat from the heating element, an endless belt extending along the heating element in the first direction, a backup member extending along the heating element in the first direction, and an adhesive. The endless belt is configured to rotate. The endless belt surrounds the heating element and the nip member. The backup member nips the endless belt in cooperation with the nip member. The adhesive is disposed between the heating element and the nip member and fixes the heating element and the nip member relative to each other.
Claims15
A fixing device comprising:
- a heating lamp extending in a first direction and configured to generate heat;
- a nip member extending along the heating lamp in the first direction and configured to receive radiant heat from the heating lamp;
- an endless belt extending along the heating lamp in the first direction and contacting a surface of the nip member opposite to the heating lamp, the endless belt being configured to rotate, the endless belt surrounding the heating lamp and the nip member;
- a backup member extending along the heating lamp in the first direction, the backup member nipping the endless belt in cooperation with the nip member;
- and
- an adhesive disposed between the heating lamp and the nip member, the adhesive fixing the heating lamp and the nip member relative to each other such that the heating lamp is disposed at a distance corresponding to a thickness of the adhesive, relative to the nip member in a second direction orthogonal to the first direction.
A fixing device comprising:
- a heating lamp extending in a first direction and configured to generate heat;
- a nip member extending along the heating lamp in the first direction and facing the heating lamp in a second direction perpendicular to the first direction, the nip member being configured to receive radiant heat from the heating lamp;
- an endless belt extending along the heating lamp in the first direction and contacting a surface of the nip member opposite to the heating lamp, the endless belt being configured to rotate, the endless belt surrounding the heating lamp and the nip member;
- a backup member extending along the heating lamp in the first direction, the backup member nipping the endless belt in cooperation with the nip member;
- a particular holding member holding the heating lamp;
- and
- a particular adhesive disposed between the nip member and the particular holding member holding the heat lamp and fixing the nip member and the particular holding member holding the heating lamp relative to each other.
