ABSTRACT:
An image forming device whereby stable fixing performance is obtained and whose fixing properties are excellent and that does not produce curling of the paper after fixing, due to performing control for correcting fixing temperature by environmental sensing not only during standby but also over time. A plurality of temperature detecting units are provided in the fixing device and a plurality of detecting units that detect temperature and humidity are provided within the image forming device. Temperature correction is performed whereby the target control temperature of the fixing device is changed to a prescribed value in accordance with the temperature or humidity detected by the plurality of detecting units.
