体の除電装置。[Scope of Utility Model Registration Claim] A plurality of recesses facing the surface of a photoreceptor and arranged along the width direction of the photoreceptor, a light source disposed on the inner bottom surface of each recess, and a space between adjacent light sources. A photoreceptor static eliminator that removes static electricity from the surface of the photoreceptor that has been irradiated by the light source by selectively turning on the plurality of light sources, the partition comprising: The thickness of each recess is such that light from the light source in each recess does not leak to the adjacent recess, and at least a part of the partition extends in a direction intersecting the direction of rotation of the photoreceptor. A static eliminator for a photoreceptor, characterized in that a region is formed in which a widthwise end of a recess overlaps a widthwise end of another adjacent recess.
