Abstract
A cleaning device includes a toner storing container that stores a collected toner, a conveyance screw that conveys toner in the toner storing container, and a toner crushing member that crushes the toner accumulated in the toner storing container. The toner crushing member is formed so as to include: a supporting portion being attached above a rotation axis of the conveyance screw; and a plurality of elastic pieces each extending from the supporting portion toward the conveyance screw and being swung by a fin that rotates in association with the rotation of the conveyance screw. Each of the elastic pieces is formed with a raised portion rising toward the seal member, so that the elastic pieces come in contact with the seal member.
