摘要： A belt device includes an endless belt and a rotary driver contacting an outer circumferential surface of the belt to drive and rotate the belt. An opposed belt support is disposed opposite the rotary driver and in contact with an inner circumferential surface of the belt. A rotary belt support is disposed opposite the rotary driver via the opposed belt support and in contact with the inner circumferential surface of the belt. A belt support holder holds the opposed belt support and the rotary belt support to retain a predetermined interval between the opposed belt support and the rotary belt support. A biasing assembly presses against the belt support holder to move the opposed belt support and the rotary belt support collectively with respect to the rotary driver and bias the opposed belt support against the rotary driver.

摘要： A fixing device includes a fixing belt formed into a loop rotatable in a predetermined direction of rotation and a pressure roller disposed opposite the fixing belt. The pressure roller includes a shaft fixedly positioned and a deformable elastic layer. A fixing pad is disposed inside the loop formed by the fixing belt and separably pressed against the pressure roller via the fixing belt to form a fixing nip between the fixing belt and the pressure roller, through which a recording medium bearing a toner image is conveyed. A biasing member biases the fixing pad and the fixing belt against the pressure roller. A stopper restricts motion of the fixing pad biased by the biasing member. The stopper contacts the fixing pad while the recording medium bearing the toner image is conveyed through the fixing nip.

摘要： A fixing device includes a drive roller, a driven roller driven to rotate by the drive roller, and a braking force applicator. The driven roller presses against the drive roller to form an area of contact between the drive roller and the driven roller, through which a recording medium bearing a toner image passes. The braking force applicator applies a braking force to the driven roller to generate a shear force between the drive roller and the driven roller. The shear force acting between the drive roller and the driven roller when the drive roller and the driven roller rotate is in a range of from 15N to 25N.

A nip formation pad contacting a first part of an inner circumferential surface of the belt presses against the opposed rotary body via the belt to form a fixing nip between the belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A heat conductor disposed opposite a second part of the inner circumferential surface of the belt not contacted by the nip formation pad is interposed between a heater and the belt to conduct heat from the heater to the belt. A reflector disposed inside the loop formed by the belt reflects light from the heater toward the heat conductor. The reflector and the heat conductor surround the heater.
