摘要： A fixing device fixes a toner image on a recording medium by heating the recording medium, with a heating area and a non-heating area selected in accordance with a magnetic flux and a repulsive magnetic flux. The fixing device includes a heat generating layer, an exciting coil, and a demagnetizing member. The heat generating layer generates heat. The exciting coil generates the magnetic flux, and thereby inductively heats the heat generating layer. The demagnetizing member faces the heat generating layer in the non-heating area. The demagnetizing member generates the repulsive magnetic flux against the magnetic flux generated by the exciting coil, and thereby demagnetizes the magnetic flux and suppresses the heating. Further, the demagnetizing member has a demagnetization effect different between at least a portion of the non-heating area adjacent to the heating area and the remaining portion of the non-heating area.

摘要： An image forming apparatus includes an oil input device and a fixing device including a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil supply member provided adjacent to an oil storage member supplies oil sent from the oil storage member to the oil application member. When the fixing device is reattached to the image forming apparatus after the fixing device is detached from the image forming apparatus, oil sent from the oil input device through an oil inlet overflows the oil storage member, and is supplied to one of the oil supply member and the oil application member provided adjacent to the oil storage member before an image forming operation starts.
