Toner conveying device, and cleaning device and image forming apparatus provided therewith

A toner conveying device, comprising:

• a toner conveying path in which toner is conveyed;
• a conveying screw that includes a rotation shaft rotatably arranged inside the toner conveying path, and a helical blade formed on an outer circumferential surface of the rotation shaft;
• and
• a flicker in which a large number of contact pieces are formed at predetermined intervals along an axial direction of the conveying screw, the contact pieces being swingable in contact with an outer circumferential surface of the conveying screw,
• wherein
• the flicker includes
• a plurality of first contact pieces that contact the conveying screw and press the conveying screw in a first direction toward a bottom of the toner conveying path, and
• a plurality of second contact pieces that contact the conveying screw from a side opposite to the first contact pieces and press the conveying screw in a second direction opposite to the first direction;
• and
• a force with which the first contact pieces press the conveying screw is greater than a force with which the second contact pieces press the conveying screw.
