Abnormality detection device and image forming apparatus
An abnormality detection device is configured to detect abnormality in a subject to be driven by a motor via a drive transmission member. The abnormality detection device includes an output signal acquisition unit, a rotational frequency acquisition unit, and a determining unit. The output signal acquisition unit is configured to acquire a rotational frequency output signal output from the motor. The rotational frequency acquisition unit is configured to acquire a motor rotational frequency calculated from the rotational frequency output signal acquired by the output signal acquisition unit. The determining unit is configured to distinctively determine abnormality in the subject to be driven and abnormality in the motor based on the rotational frequency output signal acquired by the output signal acquisition unit and the motor rotational frequency acquired by the rotational frequency acquisition unit.
