Abstract
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.
