摘要： The fixing device using an electromagnetic induction heating (IH) method includes a fixing sleeve having a heating layer, a pressure roller to form a nip while contacting the fixing roller and rotate to drive the fixing sleeve, a temperature detector to detect a temperature on a circumference of the fixing sleeve, and an excitation coil provided near the fixing sleeve and configured to perform induction heating of the heating layer of the fixing sleeve based on the detection result from the temperature detector. The fixing device is configured to change a rotation speed of the fixing sleeve in a standby time during which the fixing sleeve, while rotating, is controlled to be heated so as to maintain a target temperature when a periodic temperature difference occurs on a circumference of the fixing rotary member and having a fluctuation amplitude larger than a predetermined value compared to the target temperature.

摘要： A fixing device includes a fixing member, an induction heating unit, a pressing member, and a damage detection unit. The fixing member heats a toner image on a recording medium to fix the toner image onto the recording medium. The induction heating unit heats the fixing member by electromagnetic induction. The pressing member presses the fixing member to form a fixing nip portion. The fixing member includes a heat insulating elastic layer and a sleeve layer. The sleeve layer is located outside the heat insulating elastic layer and is provided with an outer conductive layer that generates heat from a magnetic flux generated by the induction heating unit. The damage detection unit is connected to the outer, conductive layer.

摘要： A fixing device includes an image surface side separating member that separates a recording medium from a fixing member; an image surface side conveyance guiding member arranged downstream of the image surface side separating member; a non-image surface side separating member that separates the recording medium from a pressing member; and a non-image surface side conveyance guiding member arranged downstream of the non-image surface side separating member. When the image surface side conveyance guiding member is rotated about its rotation axis so as to be opened or closed, the image surface side separating member is also rotated or slid so as to be opened or closed simultaneously. When the non-image surface side conveyance guiding member is rotated about its rotation axis so as to be opened or closed, the non-image surface side separating member is also rotated or slid so as to be opened or closed simultaneously.
