Abstract
An image forming apparatus includes a fixing device, a controller, and a storage. The fixing device includes a fixing part that fixes a toner image on a sheet, a heating part that heats the fixing part, and a detecting part that detects an actual temperature of the fixing part. The controller controls the actual temperature of the fixing part based on a target temperature of the fixing part and a cumulative deviation of the actual temperature of the fixing part. The storage stores a convergence value of the cumulative deviation. Every time a heating operation to the fixing part by the heating part is executed, the controller updates the convergence value of the cumulative deviation stored in the storage by a convergence value of the cumulative deviation of a latest heating operation.
