Abstract

A detecting apparatus includes first and second light emitting elements configured to emit light on a recording material, and a light receiving unit configured to receive the light transmitted through the recording material. The apparatus also includes a rotation member configured to rotate and press the recording material, on which the first light and the second light is emitted, against a conveyance guide for guiding the recording material. As viewed in a rotational axis direction of the rotation member, a first light path connecting the first light emitting element with the light receiving unit and a second light path connecting the second light emitting element with the light receiving unit overlap with the cylindrical member.
