A cleaning device (1) is described being part of a copying or printing system for removing residual developer from the surface of an image-delivering member (5). The device (1) comprises a cleaning brush (2) in rolling contact with the surface of the image-delivering member (5) for removing residual developer therefrom, the cleaning brush (2) being rotatable in a first predetermined direction. A collecting roller (4) is in rolling contact with the revolving brush (2), the collecting roller (4) being rotatable in a second predetermined direction. Means for biasing the collecting roller (4) are provided to generate an electrical field which attracts the residual developer from the cleaning brush (2) and collects it onto its surface. A cleaning blade (7) has a forward end portion in frictional contact with the collecting roller (4). The cleaning blade (7) is in contact with the collecting roller (4) at a contact position where the collecting roller (4) is moving in an upward direction, the cleaning blade (7) being mounted such that the contact angle (8) is less than 90 degrees. Also disclosed is a method for removing developer from a surface of an image-delivering member (5). <IMAGE> |
