PROBLEM TO BE SOLVED: To prevent a deflection amount of a transfer material from becoming inappropriate when a roller diameter varies depending on temperature of a fixing unit 170 and thus a transfer material conveying speed varies in the fixing unit 170.SOLUTION: An average speed of a fixing motor 225 when both a transfer unit 140 and the fixing unit 170 hold and convey the transfer material is calculated, and a speed serving as a reference speed when the next transfer material is conveyed is determined on the basis of the average speed. |
