    Abstract: An image forming apparatus includes a heating device, a motor, and circuitry. The heating device includes a belt, a heater, belt holders, a slide aid, lubricant, and a temperature sensor. The heater heats the belt. The belt holders hold both ends of the belt in a longitudinal direction of the belt. The inner circumferential surface of the belt slides on the slide aid. The lubricant is adhered to the belt. The temperature sensor detects a temperature of the belt. The motor rotates the belt in a forward direction to convey a recording medium and a reverse direction opposite to the forward direction. The circuitry is configured to control the motor to rotate the belt in the reverse direction in response to a detection of the temperature equal to or higher than 50° C. by the temperature sensor.

  • Patent number: 12063102
    Abstract: If reception quality of a broadcast signal of a first frequency received by a tuner satisfies setting conditions, the frequency received by the tuner is changed from the first frequency to a second frequency. It is evaluated whether or not the amount of offset between a reference frequency and the frequency of the signal, which is generated by converting the broadcast signal of the second frequency received by the tuner into an intermediate frequency is within a predetermined range. If the offset between the reference frequency and the frequency of the intermediate frequency signal is within the predetermined range, the data included in the broadcast signal of the first frequency is acquired by a demodulating the broadcast signal of the first frequency. It is evaluated whether or not the broadcast signal of the first frequency is a broadcast signal of a broadcasting station based on the acquired data.
