Abstract
A recording material determination device includes an ultrasonic wave transmission unit configured to transmit an ultrasonic wave to a recording material based on a driving signal, an ultrasonic wave receiving unit configured to receive the ultrasonic wave, a light exposure unit configured to expose the recording material to light, a light receiving unit configured to receive light, an amplification unit configured to amplify an ultrasonic wave received by the ultrasonic wave receiving unit to a first output value, and after the amplification unit amplifies the ultrasonic wave received by the ultrasonic wave receiving unit to the first output value, a control unit performs control so as to obtain the second output value by the light exposure unit and the light receiving unit during a period of time after the amplification of the ultrasonic wave is stopped and before the next ultrasonic wave comes to be transmittable.
