| 摘要 |
An embodiment of the present invention relates to a fuser unit including first and second temperature detecting mechanisms that detect the temperature at the center in an axial direction of a first roller member in non-contact with the first roller member, a third temperature detecting mechanism that detects the temperature at an end in the axial direction of the first roller member and in an area where a developer carried by a bearing member is not present, and fourth and fifth temperature detecting mechanisms that detect the temperature at the center in an axial direction of a second roller member in non-contact with the second roller member. The detecting mechanism that detects the temperature in the area (the position) where the developer carried by the bearing member is not present may come into contact with the first roller member.
