摘要： An image forming apparatus includes a fixing device, a number-of-revolutions determining unit, and a stopping unit. The fixing device includes a toner image forming unit that forms a toner image, a fixing member that fixes toner to a recording medium, a pressure member that conveys the recording medium, a driving unit that rotates the pressure member to allow the fixing member to perform slave rotation, and a number-of-revolutions sensing unit that senses the number of revolutions of the fixing member. The number-of-revolutions determining unit determines, based on the number of revolutions of the fixing member sensed by the number-of-revolutions sensing unit, the number of revolutions of the driving unit. The stopping unit stops the driving unit when the number of revolutions determined by the number-of-revolutions determining unit is not equal to a specific number of revolutions.

摘要： A rotatable-member-supporting structure includes a first rotatable member having a shaft portion, a bearing member by which the shaft portion of the first rotatable member is rotatably supported, a pressing member that presses the bearing member in one direction, and a supporting member by which the bearing member is supported in such a manner as to be retractably movable in the direction in which the pressing member presses the bearing member. A pressing force generated by the pressing member is greatest in a portion of the bearing member that is on a downstream side in a direction of rotation of the first rotatable member with respect to an intersection between the bearing member and a first virtual line extending from a center of rotation of the first rotatable member toward the pressing member in the direction in which the supporting member is retractably movable.
