置。[Claims for Utility Model Registration] In a static eliminator for removing residual charges on a photoreceptor of an electrophotographic image recording device, a plurality of light emitting diodes are arranged at predetermined intervals along the longitudinal direction of the photoreceptor at an angle of illumination. Disposed on a substrate so that the center line is parallel to the rotation axis of the photoreceptor, and on the substrate, the irradiated light corresponding to each of the light emitting diodes is partially overlapped with each other at an angle wider than the irradiation angle. A static eliminator comprising a reflective member that reflects light onto the surface of the photoreceptor.
