Claims

[Claims for Utility Model Registration] Static electricity removal used in image forming devices that removes static electricity from paper by bringing brush bristles made of a large number of single threads protruding from a holding member close to or in contact with the surface of the paper after transfer by a transfer device. In the brush, the base portions of the brush bristles are held between flexible members with the tips protruding, and the end portion of the guide member that receives and guides the transferred paper and has a conductive surface is placed close to the transfer device. 2. A static eliminator brush, characterized in that the holding member is inserted and held in a recess formed in such a manner that the tips of the brush bristles face the paper.
