An image forming apparatus (100) includes image forming means (3), a heat source (51, 55), a fixing rotating body (52) receiving heat supplied from the heat source, a pressurizing rotating body (54) adapted to form a nip portion (57) with the fixing rotating body, feeding means (42, 43, 44) for feeding a medium, temperature adjusting means (56, 6) for controlling an amount of heat generated by the heat source such that the temperature of fixing rotating body attains to a prescribed value, and control means (6). The control means switches between a first mode in which the fixing rotating body and the pressurizing rotating body rotate at a first circumferential speed and the medium is fed to the image forming means at a first distance interval, and a second mode in which the fixing rotating body and the pressurizing rotating body rotate at a second circumferential speed higher than the first circumferential speed and the medium is fed to the image forming means at a second distance interval longer than the first distance interval. |
