Abstract
A recording material determination apparatus includes a first detection unit configured to detect a characteristic corresponding to a surface condition of a recording material based on a captured image of a surface of the recording material, a second detection unit configured to detect a characteristic corresponding to a grammage of the recording material based on an ultrasonic wave detected via the recording material by irradiating the recording material with an ultrasonic wave, and a conveyance unit configured to convey the recording material. The first detection unit and the second detection unit are located opposite each other with respect to the conveyance unit.
