Abstract: A cleaning device includes an accommodating container, a collector, and a remover. The accommodating container has an opening and a receiving port. The collector is in contact with a surface of a cleaned body while rotating, to remove matter on the surface of the cleaned body. The remover has a tip end that is in contact with the surface of the cleaned body to remove the matter. The accommodating container accommodates the collector and the remover. The collector and the remover are exposed to the cleaned body through the opening. The accommodating container receives, through the receiving port, the matter removed from the cleaned body. The accommodating container is supported in such a manner that the accommodating container can rotate to a position where the matter collected in the accommodating container do not leak through the opening, so as to be separated from the cleaned body.
