To solve the problem that an object to be inspected is not accurately detected because of the soiling on an optical means and kinds of the object to be inspected, as for an optical detector for an image forming device, which is provided with optical means such as a light emitting means, a light receiving means, a reflecting means, etc., and is for optically detecting the object to be inspected such as a paper, etc., by the optical means.
A conductive adsorption means connected at a prescribed potential is arranged near the optical means, and the optical means is attached to periodical replacement parts for the image forming device. The reflecting means 20b and a paper carrying path are arranged opposite to the light receiving means 20d, and a distance from the light emitting means 20c, etc., to the reflecting means 20b is made to differ from a distance from the light emitting means 20c to the paper carrying path.
