Abstract
A cleaning device includes a case, a rotating member, a sheet member, and a cover member. The rotating member includes a peripheral face which comes into contact with the cylindrical face of an image carrier, is rotatively driven in a same direction as the image carrier at a contact position, and recovers a toner which has attached on the image carrier. The sheet member extends toward a direction approaching a straight line that connects the rotating axis of the image carrier and the contact position of the rotating member, and includes a leading end which comes into contact with the cylindrical face. The cover member is provided in the case so as to cover an upside of the sheet member, extends toward the direction approaching the straight line, and reaches a position above the leading end of the sheet member.
