图像形成装置
摘要：
本发明提供一种在卡纸处理后使图像形成能够顺利地再次开始的图像形成装置。该图像形成装置具有：图像形成部、定影部、门80、产生定影部中夹持部的按压力的弹性部件、以及改变弹性部件的按压状态的切换部件86。切换部件可取第一位置、第二位置或第三位置。使加持部的按压力在第一位置成为第一级别。在第二位置成为与第一级别不同的第二级别。在第三位置成为小于所述两级别中较低一方以下的按压力。另外，门上设有干涉部件87。在门从打开状态向关闭状态移动时，在切换部件位于第一位置或第二位置的情况下，干涉部件不与切换部件干涉，在切换部件位于第三位置的情况下，干涉部件与切换部件干涉，以使切换部件向第一位置移动。
摘要（英）：

The invention discloses an image forming apparatus which enable smooth starting of image forming after handling a paper jam. The image forming apparatus includes an image forming unit, a fixing unit, a door 80, an elastic member to generate a pressing force of a nip portion of the fixing unit, and a switching member 86 to change a pressing state of the elastic member. The switching member is placed in any one of first, second, and third positions. In the first position, the pressing force is defined as a first level. The second position has a second level different from the first level. The pressing force of the third position is equal to or lower than the smaller one of the first and second levels. Also, the door is provided with an interference member 87. While the door is closed from open state, the interference member of the door does not interfere with the switching member in the first or second position but interferes with the switching member in the third position to move the switching member to the first position.
