Abstract:
1. A fixing device that includes (i) a heat generating rotational body that includes a resistive heat layer that generates heat by receiving power supply and (ii) a pressing rotational body, forms a fixing nip by pressing the pressing rotational body against an outer circumferential surface of the heat generating rotational body, and feeds a sheet on which an unfixed image is formed through the fixing nip to thermally fix the image, the fixing device comprising: a power non-receiver that is provided on a part of at least one of outer circumferential regions on respective edge portions of the heat generating rotational body, the outer circumferential regions being other than a sheet passing region of the heat generating rotational body; power receivers that are provided on the respective outer circumferential regions excluding the part on which the power non-receiver is provided; a driver configured to rotate the heat generating rotational body; power feeding members that are in contact with and supply power to the respective power receivers; and a controller configured, when a predetermined power interrupting condition is satisfied, to cause the driver to rotate the heat generating rotational body until the power non-receiver faces at least one of the power feeding members so that the power supply to the heat generating rotational body is interrupted.
