Patent ID: 7369787

Claim:
An image forming apparatus, comprising: a heating rotator that is heated by a first heat source; a pressurizing rotator that is heated by a second heat source, that is in pressure contact with the heating rotator, and that forms a fixing nip between the pressurizing rotator and the heating rotator; a temperature sensor that detects an ambient temperature in the apparatus; and a controller that increases intervals between paper sheets being continually passed through the fixing nip so that the intervals may be larger than a normal value on condition that the temperature detected by the temperature sensor exceeds a specified value, wherein the controller carries out control for increasing a temperature of the pressurizing rotator on condition that the temperature detected by the temperature sensor exceeds a specified value and the controller carries out control for decreasing a temperature of the heating rotator simultaneously when increasing a temperature of the pressurizing rotator on condition that the temperature detected by the temperature sensor exceeds a specified value.
