摘要： A fixing device for fixing an unfixed toner image on a recording medium includes a fixing member, a pressure member, a sheet guide, and a pressure adjusting mechanism. The fixing member heats the unfixed toner image on the recording medium. The pressure member is disposed opposite the fixing member and presses against the fixing member to define a fixing nip through which the recording medium bearing the unfixed toner image passes to fix the unfixed toner image onto the recording medium. The position of the fixing nip is changeable. The sheet guide disposed adjacent to the pressure member guides the recording medium to the fixing nip and moves in conjunction with movement of the pressure member. The pressure adjusting mechanism operatively connected to the pressure member adjusts an amount of engagement of the pressure member relative to the fixing member. An image forming apparatus includes the fixing device.

摘要： An elastic layer is provided on a surface of one of a metal core and a substrate. A fixing member and a pressure member press into each other and collectively create a nip therebetween. A toner image is conveyed and fixed when passing through the nip. A thickness of the elastic layer is different in at least two widthwise regions by the same amount from the other region. A pair of edges of a prescribed size of the transfer sheet pass through these two widthwise regions, respectively.

The rotating heat generation member rotates and applies heat to a recording medium bearing an image, and includes a heat-generating layer to generate heat using the magnetic flux generated by the magnetic flux generator. The magnetic flux adjuster is provided outside the rotating heat generation member, and decreases the magnetic flux applied to the heat-generating layer at least in a desired area in an axial direction of the rotating heat generation member. The driver changes the desired area by driving the magnetic flux adjuster in a direction of rotation of the rotating heat generation member.

摘要： A fixing device includes an excitation coil, a heat-generating layer, a magnetic shunt layer, and a degaussing member. The excitation coil generates a magnetic flux. The heat-generating layer generates heat using the magnetic flux generated by the excitation coil. The magnetic shunt layer transmits heat generated by the heat-generating layer. The degaussing member sandwiches the magnetic shunt layer together with the excitation coil, and selectively performs degaussing by generating a repelling magnetic flux for canceling the magnetic flux generated by the excitation coil so as to activate a self-temperature-control function. The degaussing member selectively refrains from degaussing so as to deactivate the self-temperature-control function.
