Abstract
A fixing device for fixing a toner image onto a recording sheet, the fixing device comprising: a fixing belt including, on an inner circumference side thereof, a resistance heating layer, extending over entire circumference of the fixing belt, operable to emit heat upon flowing of an electric current therethrough; a pressing member operable to press an outer circumference of the fixing belt to form a fixing nip therebetween so that, while the recording sheet passes through the fixing nip, the toner image is fixed onto the recording sheet; and a pair of power supply members arranged inside the fixing belt along the circumferential direction with a predetermined distance therebetween, the power supply members being in contact with the inner circumferential surface of the resistance heating layer in an electrically conductive state along a direction perpendicular to the circumferential direction.
