定影装置及图像形成装置
摘要：
本发明提供一种定影装置和图像形成装置，在使用筒状定影构件时，即使对其进行高速回转，也不会使得轴线方向的端部屈曲或破损，从而能够稳定地回转。其在与未定影调色剂接触后回转的定影套筒(31)和加压辊之间形成定影夹持部并具有加热定影套筒的加热机构，并将载置有未定影调色剂的片材状的记录材料通过定影夹持部后来进行定影，在定影套筒的回转轴线(L)方向的两端部(31a)，(31b)中分别设置从定影套筒的外周面向外侧突出的偏靠防止构件(39)，在定影套筒的至少将两端部支持为可以回转的法兰构件(15)侧里，设置了分别从外侧来钩挂所述各偏靠防止构件后以牵拉状态来阻止定影套筒向回转轴线方向偏靠的止挡构件(43)。
摘要（英）：

The invention provides a fixing device and an image forming apparatus. When the cylindrical fixing member is used, the end part in the axis direction will not be bent or destroyed even if the fixing member is in high speed rotation, and thus the rotation is stable. A fixation clamping part is formed between a fixing sleeve (31) and a pressing roller, and is provide with a heating fixing sleeve. A sheet-shaped recording material, which is provided with an unfixed coloring agent, is subjected to fixation through the fixation clamping part. Two end parts (31a) (31b) are both provided with a deviation preventing members (39) that extends outwardly from the external circumferential surface. In the side, which is provided with a flange member (15) for supporting the rotation of the two end parts of the fixation sleeve, a stop member (43) for hooking the deviation preventing members is arranged, so that the deviation preventing members can be pulled back so as to preventing the fixation sleeve from going to the rotation axis.
