Abstract
A sensor is attached to an apparatus having a fixing unit which fixes an image on a recording medium by heating the recording medium. The sensor includes: a transmission unit transmitting an ultrasonic wave to the recording medium; a reception unit receiving the ultrasonic wave via the recording medium, and output a signal corresponding to the received ultrasonic wave; and a detecting unit detecting information relating to a state of the recording medium which has changed by passing through the fixing unit, based on a first signal which the reception unit has output upon having received the ultrasonic wave before the recording medium has passed through the fixing unit, and a second signal which the reception unit has output upon having received the ultrasonic wave after the recording medium has passed through the fixing unit.
