摘要：An image forming apparatus which has a structure such that the oil consumption in a detachable and changeable oil supply means is accurately predicted to display appropriate change timing. This prevents continuation of a fixing operation when the fixing cannot be performed because oil has been consumed. The result is a reliable fixing operation in which offset is prevented. The oil consumption of a detachable oil supply means is predicted using at least any one of size, material, and printing mode information. Oil consumption is used to calculate and predict the integrated value of the predicted oil consumption. If the integrated value of the predicted oil consumption exceed a predetermined value, display to change the oil supply means is performed. After change has been displayed, the image forming apparatus is interrupted. <IMAGE>
