Neutralization device and image forming apparatus

A neutralization device that irradiates a surface of an electrically charged image carrier with neutralization light to discharge electricity of the image carrier, the neutralization device comprising:

• a housing;
• a substrate that is connected to the housing;
• light emitting portions that are mounted on the substrate, and emit neutralization light;
• a first end engagement portion that is engaged with a first end portion that is an end portion of the substrate opposite to the image carrier;
• a partitioning member, which is disposed to interpose the substrate between the partitioning member and the housing, and which is connected to the housing on a base end portion side, so as to form an opened portion that is opened to face the surface of the image carrier;
• and
• a plurality of restriction protrusions that are arranged along an axial direction of the image carrier, between the surface of the image carrier and a second end portion that is an end portion opposite to the first end portion of the substrate,
• wherein the first end engagement portion is disposed in a central portion of the plurality of restriction protrusions in an arrangement direction, and
• wherein the arrangement direction of the plurality of restriction protrusions curves in a holoscopic view, such that a central portion of the restriction protrusions in the axial direction is closer to the image carrier than end portions of the restriction protrusions in the axial direction.
