Static elimination apparatus and image forming apparatus

A static elimination apparatus comprising:

• a conveyance unit configured to convey a sheet along a conveyance path;
• a non-contact static elimination unit configured to eliminate static from the sheet in a state where the non-contact static elimination unit is not in contact with the sheet conveyed by the conveyance unit;
• a first guide member including a contact portion configured to guide the sheet while contacting the sheet conveyed by the conveyance unit, and a plurality of openings arranged next to each other in a width direction of the sheet orthogonal to a sheet conveyance direction and configured to expose the non-contact static elimination unit to the conveyance path, wherein the first guide member serves as a part of the conveyance path;
• and
• a second guide member arranged to be opposed to the first guide member and serving as the part of the conveyance path with the first guide member,
• wherein the contact portion includes a plurality of first ribs arranged on one side with respect to a conveyance center in the sheet width direction, and a plurality of second ribs arranged on the other side with respect to the conveyance center in the sheet width direction, and
• wherein the plurality of first ribs and the plurality of second ribs are inclined relative to the sheet conveyance direction so that the further downstream in the sheet conveyance direction each rib is, the greater a distance between each rib and the conveyance center is.
