A recording material image capture device includes light sources radiating light to a recording material, an image capture element receiving the light which is reflected on a surface of the recording material, a cover member provided between the image capture element and the recording material so that the reflected light passes through the cover member, a roller pressing the recording material toward the cover member, and an output portion outputting, based on an image captured by the image capture element, a value related to the recording material to which the light is radiated. The roller is a rotating member which rotates along with movement of the recording material, and the roller includes a recess portion which is prevented from contacting with an entire portion corresponding to the image used for determining the recording material, and projecting portions which are brought into contact with the recording material.
