Cleaning device, and image carrier unit and image forming apparatus having same

摘要

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.

主权项

1. A cleaning device which is disposed above an image carrier including a rotating axis, and a cylindrical face rotating in one direction around the rotating axis and carrying a toner image, and which cleans the cylindrical face, the cleaning device comprising:
a case; a rotating member provided in the case and including a peripheral face that comes into contact with the cylindrical face above the rotating axis in a cross section view that is orthogonal to the rotating axis, is rotatively driven in a same direction as the image carrier at a contact position that comes into contact with the cylindrical face, and recovers a toner that has attached on the image carrier; a sheet member provided in the case and extending horizontally, in the cross section view, from a position that is above the rotating axis and separated from the cylindrical face 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 on a side that is further upstream in the rotating direction of the image carrier than the rotating member; and a cover member provided in the case directly above the sheet member so as to cover an upside of the sheet member, the cover member extending horizontally from a position that is separated from the cylindrical face in the cross section view toward the direction approaching the straight line, the cover member reaching a position over the leading end of the sheet member and extending farther toward the direction approaching the straight line than the leading end of the sheet member in a protruding manner.
