とする画像形成装置のクリーニング装置。 A first rotating brush including a brush member to which a potential of the same polarity as the potential of the toner is applied, and a second rotating brush to which a potential of the opposite polarity to the potential of the toner is applied.
The first rotating brush is located upstream in the rotational direction of the photoreceptor and is provided in the cleaning case, and the brush members of the two rotating brushes are caused to interfere with each other and rub against the surface of the photoreceptor, and The direction of rotation of the first rotating brush in the rubbing area against the photoreceptor is set in the same direction as the direction of rotation of the photoreceptor, and the direction of rotation of the second rotating brush is set in the opposite direction, and the two rotating brushes are A toner collection roller is provided on the opposite side of the photoreceptor across the interference region of the brush member to which a potential of opposite polarity to the potential of the toner is applied while providing a peripheral speed difference, and further,
A cleaning device for an image forming apparatus, comprising a toner peeling member for peeling toner from a peripheral surface of the toner collection roller.
