Abstract:
In accordance with one embodiment, an image forming apparatus comprises a fixing device and a control section. The fixing device is provided with a fixing roller for conveying a sheet. The control section changes the rotation speed of the fixing roller based on a shrinkage rate of the sheet before and after the passing of the sheet through the fixing device. The control section changes, according to the shrinkage rate, the rotation speed of the fixing roller in the second and the following fixing processing carried out by the fixing device in a case in which the same sheet passes through the fixing device more than twice.
