摘要： A fixing device includes: a fixing roll that is rotatable; a belt member that is stretched over the fixing roll; a pressurizing roll that pressurizes the fixing roll via the belt member; a belt pressing member that presses an outer surface of the belt member to the pressurizing roll from inside of the belt member on a downstream side at a pressure-contact position between the fixing roll and the pressurizing roll; and a controller that decrease a time difference between a passage time per unit area of a tip region of a recording medium and a passage time per unit area of a succeeding region of the recording medium to pass a pressure-contact portion between the fixing roll and belt pressing member and the pressurizing roll.
