Abstract
A reflector includes a reflecting portion, a pressure receiving portion, and a connecting portion. The reflecting portion is in a rotator of a heating device and reflects heat from a heater in the rotator. The pressure receiving portion is in the rotator and receives pressure via the rotator from a pressure rotator of the heating device. The pressure rotator is outside the rotator. The pressure receiving portion is thermally connected to the reflecting portion. The connecting portion connects the reflecting portion and the pressure receiving portion. At least one of the pressure receiving portion or the connecting portion has a hole.
Claims16
A reflector comprising:
- a reflecting portion in a rotator of a heating device, the reflecting portion to reflect heat from a heater in the rotator;
- a pressure receiving portion, in the rotator, to receive pressure via the rotator from a pressure rotator, of the heating device, outside the rotator, the pressure receiving portion thermally connected to the reflecting portion;
- and
- a connecting portion connecting the reflecting portion and the pressure receiving portion,
- wherein at least one of the pressure receiving portion or the connecting portion has a hole.
A reflector comprising:
- a reflecting portion in a rotator of a heating device, the reflecting portion to reflect heat from a heater in the rotator;
- a pressure receiving portion, in the rotator, to receive pressure via the rotator from a pressure rotator, of the heating device, outside the rotator, the pressure receiving portion thermally connected to the reflecting portion;
- and
- a connecting portion connecting the reflecting portion and the pressure receiving portion,
- wherein at least one of the pressure receiving portion or the connecting portion has a groove.
A reflector comprising:
- a reflecting portion in a rotator of a heating device, the reflecting portion to reflect heat from a heater in the rotator;
- a pressure receiving portion, in the rotator, to receive pressure via the rotator from a pressure rotator, of the heating device, outside the rotator, the pressure receiving portion thermally connected to the reflecting portion;
- and
- a connecting portion connecting the reflecting portion and the pressure receiving portion,
- wherein at least one of the pressure receiving portion or the connecting portion includes a first portion having a first thermal conductivity,
- the reflector has a second portion, other than the first portion, and
- the second portion has a second thermal conductivity higher than the first thermal conductivity.
