Abstract
A cleaning device comprises: a to-be-cleaned member; a cleaning member that cleans the surface of the to-be-cleaned member; a conveying member that conveys a substance removed from the surface of the to-be-cleaned member to outside of the device; a rotatable collecting member that conveys with its surface the substance toward the conveying member; and a partitioning member that guides the substance from the collecting member to the conveying member. The collecting member comprises a conveying portion that carries and conveys the substance; and a protrusion that protrudes toward an upstream side of the conveying portion in a rotating direction of the collecting member. One end of the partitioning member faces the rotating collecting member, and the other end faces the conveying member. The conveying portion and the protrusion are brought into contact with the partitioning member by the rotation of the collecting member.
