<p>PROBLEM TO BE SOLVED: To carry a transfer material having a toner image transferred on both front and back sides to a fixing device without any contact between the toner image and equipment and fix the same by heat press-fixing without generating any wrinkles. SOLUTION: A driving roller 14d for carrying a toner image receiver 14a by circulating the same and the press-fixing roller 17b of a fixing device are both formed to be crown shaped and, when a transfer material is separated by the curvature part of the toner image receiver 14a, flatness is maintained for the transfer material by slightly projecting the same in shape by the crown shape of the driving roller 14a and thus the transfer material is carried to the fixing device without generating any wrinkles or distortion and, further, the tendency of the transfer material is strengthened by the crown shape of the press-fixing roller 17b, wrinkles are prevented even during press-heating.</p> |
