摘要： In a motor control apparatus, an exciting unit excites a plurality of excitation phases of a motor. A current measurement unit measures exciting currents flowing through coils of respective phases of the motor, and generates measurement data including measurement values of the exciting currents. A determination unit determines whether or not noise is superimposed on a measurement value included in the measurement data by comparing, with respect to each of the plurality of excitation phases, the measurement data regarding a first phase coil that constitutes that excitation phase with the measurement data regarding a second phase coil that constitutes that excitation phase.

摘要： In a fixing device, an alternating current is caused to flow through a coil so as to causes an electrically conductive layer of a rotating member to generate heat, and an unfixed image on a recording medium is heat fixed onto the recording medium by the heat generated by the electrically conductive layer. A frequency range of the alternating current is from 20.5 kHz to 100 kHz. With respect to a generatrix direction of the rotating member, a magnetic member and a spirally shaped portion of the coil have lengths, with which the magnetic member and the spirally shaped portion extend beyond both end portions of the rotating member.

摘要： A fixing apparatus to fix a toner image formed on a recording material to the recording material includes a rotatable member having a heat generation layer, a power supply circuit, and a control unit. The power supply circuit supplies electrical power to the rotatable member. The control unit controls supply of electrical power to the rotatable member and detects a change rate of electrical resistance of the heat generation layer. The heat generation layer generates heat by the electrical power supplied to the rotatable member, and the toner image on the recording material is fixed to the recording material by the heat from the heat generation layer. If the change rate of the electrical resistance to the supplied electrical power is higher than a predetermined threshold, the control unit stops the supply of electrical power to the rotatable member.
