摘要： A fixing device and image-forming apparatus, which provide required glossiness and paper adaptability, and, in addition, feature good operability and excellent durability while achieving optimal pressure-applying force for a variety of requirements. The fixing device has a pressure-applying lever; a pressure-releasing lever; a locking member, the one end of which is rotationally attached to the pressure-releasing lever; and an elastic member which pulls the locking member in a locking direction. The configuration is such that the rotation of the pressure-releasing lever displaces the location of the locking member, thereby enabling switching between a pressure-applying position, in which a fixing member presses against another fixing member, and a pressure-releasing position, in which the one fixing member moves away from the other fixing member.

摘要： 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.

摘要： A fixing device includes a fixing rotary body to rotate in a predetermined direction of rotation and a pressing rotary body pressed against the fixing rotary body to rotate in a direction counter to the direction of rotation of the fixing rotary body and form a nip therebetween through which a recording medium bearing a toner image passes. A heat generator is disposed opposite the fixing rotary body at a section other than the nip to heat the fixing rotary body. A moving assembly is disposed opposite the heat generator to generate a magnetic force to move the heat generator with respect to the fixing rotary body so as to change one of a pressure and a distance between the heat generator and the fixing rotary body.
