Abstract
A fixing device that includes a heater, a first endless belt, a first roller, and a second roller is provided. The first endless belt confronts the heater at a confronting part and providing a nip region upon contacting the heater. The first endless belt is movable in a first direction at the confronting part, and has an inner peripheral surface. The first roller supports the inner peripheral surface, and nips the first endless belt in cooperation with the heater. The nip region has a part facing the first roller. The second roller is disposed downstream of the nip region in the first direction and supports the inner peripheral surface. The second roller is positioned such that a part of the endless belt mounted over the second roller is out of contact from the heater.

- a heater;
- a first endless belt confronting the heater at a confronting part and providing a nip region upon contacting the heater, the first endless belt being movable in a first direction at the confronting part, and having an inner peripheral surface;
- a first roller supporting the inner peripheral surface, and nipping the first endless belt in cooperation with the heater, the nip region having a part facing the first roller;
- and
- a second roller disposed downstream of the nip region in the first direction and supporting the inner peripheral surface, the second roller being positioned such that a part of the first endless belt mounted over the second roller is out of contact from the heater, assuming that the heater is positioned above the first roller, the second roller having a part positioned higher than the first roller.
A fixing device, comprising:
- a first roller;
- a second roller;
- a first endless belt arranged around the first roller and the second roller;
- and
- a heater configured to nip the first endless belt in cooperation with the first roller, and to provide a nip region upon contacting the first endless belt, a width of the nip region in a direction from the first roller toward the second roller being narrower than a distance between the first roller and the second roller.
