| 发明名称 | Fixing device and image forming apparatus including a nip-forming-member supported by at least two plates joined together | ||
| 摘要 | A device includes a fixing belt, a holder that holds the fixing belt, a pressing member that comes in contact with the fixing belt, a nip-forming-member arranged inside the fixing belt, that forms a nip by coming in contact with the pressing member, a supporting member that supports the nip-forming-member, a side plate to which the nip-forming-member and the supporting member are fixed, and a pressing mechanism that presses a pressing roller to the nip-forming-member via the fixing belt. The supporting member includes at least two plates. The two plates are separated from each other near a contact portion where the plates come in contact with the nip-forming-member. At least a part of each of the plates is a flat surface parallel to a direction of a load applied by the pressing mechanism. Portions of the two plates on a side distant from the contact portion are joined together. | ||
