An electricity removing unit 50 includes a rotating roller part 51, a brush part 52, a driving part, and a restraint member. The brush part 52 includes a plurality of conductive fiber bristles 52a having base end portions connected to a peripheral surface of the rotating roller part 51. The driving part rotationally drives the rotating roller part 51. The restraint member abuts the brush part 52 from a rotation downstream side, thereby inclining the plurality of conductive fiber bristles 52a to an upstream side from a downstream side of a rotational direction toward a radial outside and thus reforming them. In this way, the restraint member restrains a distance between a front end of each conductive fiber bristle 52a and the peripheral surface of the rotating roller part 51 to a setting distance set in advance.
