摘要： An image forming apparatus includes a fixing device that includes a heater to heat a fixing rotator, an opposed rotator to press against the fixing rotator to form a fixing nip therebetween, and at least one rotary body to convey a recording medium to the fixing nip. A controller rotates the fixing rotator in a forward direction to fix a toner image on the recording medium. The controller stops the heater and rotates the fixing rotator in a predetermined rotation direction when a failure occurs while the fixing device is activated. The controller determines that the predetermined rotation direction is the forward direction or a backward direction according to the at least one rotary body that sandwiches the recording medium, if the fixing nip and the at least one rotary body sandwich the recording medium simultaneously when the failure occurs while the fixing device is activated.

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 belt, a pressure rotator disposed opposite the belt, and a nip formation unit that forms a fixing nip between the belt and the pressure rotator. The nip formation unit includes a guide face disposed upstream from the fixing nip in a rotation direction of the belt and contoured to separate from the pressure rotator in a direction opposite the rotation direction of the belt. The guide face is adhered with a lubricant moved from an inner circumferential surface of the belt. The belt rotates in the rotation direction when an outer circumferential surface of the belt has a temperature lower than a fixing temperature at which the belt fixes a toner image on a recording medium. The belt rotating in the rotation direction brings the lubricant adhered to the guide face into contact with the belt.

摘要： A fixing device includes a heat generator being disposed inside a loop formed by a rotator and including a heat generating portion to radiate radiant heat. A reflector is disposed inside the loop formed by the rotator and includes a reflection face to reflect the radiant heat radiated from the heat generator toward the rotator. A support supports the reflector. A holder holds each lateral end of the support in a longitudinal direction of the support, which is perpendicular to the rotation direction of the rotator. A fastener attaches the reflector to the support at an attachment position disposed at each lateral end of the reflector in a longitudinal direction of the reflector. The attachment position is disposed outboard from a lateral edge of the heat generating portion of the heat generator and disposed inboard from the holder in the longitudinal direction of the reflector.
