| 发明名称 | Image heating apparatus | ||
| 摘要 | An image heating apparatus includes a rotary member, a heating member configured to heat the rotary member, the heating member being held in contact with the rotary member, a temperature detecting element configured to detect the temperature of the rotary member or the heating member, a protection element configured to interrupt power supply to the heating member, the protection element being activated when sensing an abnormal rise in the temperature of the heating member, and a control portion configured to control the image heating apparatus. When the temperature detected by the temperature detecting element exceeds a threshold value, the control portion stops rotation of the rotary member. | ||

| 主权项 | 1. An image heating apparatus, comprising: a rotary member; a heating member configured to heat the rotary member, the heating member being held in contact with the rotary member; a temperature detecting element configured to detect the temperature of the rotary member or the heating member; a protection element configured to interrupt power supply to the heating member, the protection element being activated when sensing an abnormal rise in temperature of the heating member; and a control portion configured to control the image heating apparatus, wherein, when the temperature detected by the temperature detecting element exceeds a threshold value, the control portion stops rotation of the rotary member to shorten a time required to activate the protection element. | ||
