    • An image forming apparatus of the present invention includes an apparatus body to which a conveying unit is removably mounted. A belt is used to convey a paper sheet. A sensor includes a light emitting portion for emitting light toward the belt and a photosensitive portion to which the light from the belt is incident. One of the light emitting portion and photosensitive portion is mounted on the conveying unit while the other is mounted on the apparatus body. A positioning device causes, in interlocked relation to the mounting operation of the conveying unit to the apparatus body, the optical portion mounted on the apparatus body to move in accordance with the position and/or the configuration of the conveying unit and be positioned relative to the belt. Therefore, only the conveying unit and optical portion should be positioned relative to each other.
