摘要： A belt unit is detachably attached to a housing. A holder changes a state of an endless belt by moving a transfer roller between a first state as an endless belt movement state and a second state as a detachment state. The first state allows the endless belt to circulate for image formation, and the second state allows the belt unit to be detached from the housing. The holder moves the transfer roller adjacent supporter independently of the transfer roller and lifts the opening in the endless belt to a prescribed position to expose it to the front side plate.

摘要： A fixing device includes an endless belt, a drive rotator, a driven rotator, a rotation detector, and circuitry. The drive rotator contacts and rotates the endless belt. The driven rotator contacts an inner circumferential surface of the endless belt. The rotation detector detects a rotational speed of the driven rotator. The circuitry is operatively connected to the rotation detector to control a rotational speed of the drive rotator based on the rotational speed of the driven rotator detected by the rotational detector. The circuitry changes the rotational speed of the drive rotator when a recording medium bearing a toner image is not conveyed over the endless belt.
