摘要： A fixing method is provided including the step of fixing a toner on a recording medium with a fixing device. The toner has a binder resin, a colorant, and a release agent, and has a release agent amount indicator of from 0.01 to 0.20. The release agent amount indicator is represented by a ratio (P2850/P828) of an intensity (P2850) at a wave number of 2,850 cm−1 to an intensity (P828) at a wave number of 828 cm−1 of the toner measured by a Fourier transform infrared spectroscopy attenuated total reflection method. The fixing device includes a fixing rotator driven to rotate by a driving source, a pressure rotator driven to rotate by rotation of the fixing rotator, a fixing belt interposed between the fixing rotator and the pressure rotator, and a heater to heat the fixing belt.

摘要： A separation device includes an endless belt, a rotary body, a separation supporter, and a transfer mechanism. The separation supporter presses against an inner circumferential surface of the endless belt downstream from an area of contact between the endless belt and the rotary body in a recording medium conveyance direction to curve the endless belt toward an outer circumferential surface side of the endless belt at a greater curvature than a curvature of the endless belt at the area of contact between the endless belt and the rotary body. The transfer mechanism switches the separation supporter between a first position and a second position farther from the area of contact between the endless belt and the rotary body than the first position.

摘要： An image forming apparatus includes a fixing belt stretched across a first roller and a second roller including an elastic layer. A pressure rotator presses against the second roller via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A recording medium bearing a toner image is conveyed through the fixing nip. A clearance detector detects a clearance between the first roller and the second roller. A mover moves the pressure rotator with respect to the second roller in a pressing direction in which the pressure rotator presses against the second roller via the fixing belt and a separation direction in which the pressure rotator separates from the second roller. A controller controls an amount of movement of the pressure rotator moved by the mover toward the second roller based on the clearance detected by the clearance detector.
