Abstract
A cleaning device includes a contact member that contacts a rotation surface and a lever device which displaces the contact member. The lever device includes a roller which contacts the rotation surface and a lever which supports the roller to rotate in response to a forward rotation of the rotation surface. The lever is displaced by receiving a force of the rotation surface through the roller and separates the contact member from the rotation surface, in response to a backward rotation of the rotation surface.
