Abstract
A heating roller includes: a roller cylinder rotatably disposed; a base rotatably disposed in the roller cylinder; first to third heaters, which are mounted on the base and respectively have a first heating section, a second heating section and a third heating section extending respectively in directions substantially parallel to an axial direction of the roller cylinder; and a driving mechanism, which is connected to the base and rotates the base to multiple position states. An image forming apparatus using the heating roller is also disclosed.

A heating roller, comprising:
- a roller cylinder rotatably disposed;
- a base rotatably disposed in the roller cylinder;
- first to third heaters, which are mounted on the base, and respectively have a first heating section, a second heating section and a third heating section extending in directions substantially parallel to an axial direction of the roller cylinder;
- and
- a driving mechanism, which is connected to the base and rotates the base to multiple position states, wherein first to third heating conditions different from one another are provided according to the position states in conjunction with power-on and power-off states of the first heating section, the second heating section and the third heating section, wherein in the axial direction, a second range of the second heating section covers and is larger than a first range of the first heating section, the second range ranges between two third ranges of the third heating section, and the second range is complementary to the two third ranges.
