Abstract
A surface discriminating device for a recording material includes a probe having a fixed first end portion and a second end portion capable of contacting with the recording material, the probe being adapted to contact with and move relative to the recording material to thereby scan the recording material, and a piezoelectric element provided between the first end portion and the second end portion of the probe. The surface of the recording material is discriminated by the output from the piezoelectric element during the scanning of the recording material by the probe, the probe having a bent portion on the second end portion side.
