Abstract
A fuser device includes a first motor for rotatably driving one of a heating member and a pressure-applying member, a second motor rotating either in a forward direction or a reverse direction in order to switch a pressure-application-switching mechanism between an applied-pressure state and a released-pressure state, a first detector for detecting whether the first motor is rotating, and a second detector for detecting the forward-direction or reverse-direction rotation of the second motor. The first detector has a first sensor for detecting the rotation of the first detector plate caused to rotate by the first motor. The second detector has a second sensor for detecting changes in the rotational state of the second detector plate caused to rotate in the forward and reverse directions by the second motor. A single sensor constitutes the first sensor and the second sensor.
