CONVEYANCE DEVICE, PROCESS CARTRIDGE AND IMAGE FORMATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a conveyance device, a process cartridge and an image formation apparatus which can prevent reduction in the cleaning performance due to application of pressure from developers accumulated in a cleaning frame body to a contact part and enhance the cleaning performance of the developer to a prescribed conveyance path.SOLUTION: The conveyance device for conveying a developer comprises: a cleaning member which is brought into contact with an image carrier to remove the developer on the image carrier; a storage part which stores the removed developer; a conveyance member for conveying the developer from the storage part; a sheet member which is brought into contact with the image carrier; and a wall surface of the storage part which is located on the side of the sheet member with respect to the straight line connecting the rotation center of the image carrier and the rotation center of the conveyance member in a plane orthogonal to the axial direction of the image carrier. The wall surface gets closer to the straight line as getting vertically above the wall surface. The conveyance member is located on the upper side in the gravity direction of the position where the image carrier and the cleaning member are brought into contact with each other, and the rotation direction of the conveyance member and the rotation direction of the image carrier are the same direction.SELECTED DRAWING: Figure 1
