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： An image forming apparatus includes a transfer unit, a fuser unit, a detector, and an adjustment mechanism. The transfer unit transfers an image from an imaging surface to a recording sheet passing through a transfer nip. The fuser unit fixes the transferred image in place on the recording sheet passing through a fixing nip. The transfer nip and the fixing nip form part of a sheet feed path along which a recording sheet is fed from the fuser unit to the transfer unit. The detector is located between the transfer nip and the fuser unit, and detects an amount of sheet skew by which the fed recording sheet is deviated from a proper position in the sheet feed path. The adjustment mechanism adjusts position of either or both of the transfer unit and the fuser unit according to the detected amount of sheet skew.

摘要： An image forming apparatus including a fixing device that has a rotatable endless belt, a contacting member to contact the rotatable endless belt, a rotatable pressing member contacting the contacting member via the rotatable endless belt to form a nip region, a heating member to heat the rotatable endless belt, a detecting device to detect a temperature of the heating member, a controlling device to control a temperature of the heating member based on a detection result of the detecting device, and a determining device to determine that the sheet-like recording medium has passed through the fixing device. The controlling device controls such that the temperature of the heating member set for the fixing operation is decreased to a temperature set when the sheet-like recording medium has passed through the fixing device, immediately after a last sheet-like recording medium in a series of a job has passed through the fixing device.

摘要： A fixing device includes a fixing belt, a first heater, a second heater, a supporting roller, and a counter roller. During activation of the fixing device, a maximum power is supplied to the first heater, and only the first heater heats the fixing belt. When a temperature on the fixing belt reaches a first reference temperature, the fixing belt is driven rotationally, the power supplied to the first heater is dropped, and power is supplied also to the second heater. When the temperature on the fixing belt reaches a target temperature and the temperature on the counter roller reaches a second reference temperature, fixing operation is allowed to start.

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.
