Abstract
A cleaning device, being part of a copying or printing system, for removing residual developer from the surface of an image-delivering member is described. The device includes a cleaning brush in rolling contact with the surface of the image-delivering member for removing residual developer therefrom. A biased collecting roller is in rolling contact with the revolving brush. The collecting roller is biased such as to attract the residual developer from the cleaning brush and to collect it onto its surface. A trailing cleaning blade has a forward end portion in frictional contact with the collecting roller. The trailing cleaning blade is in contact with the cleaning roller at a contact position where the collecting roller is moving in an upward direction. Also disclosed is a method for removing developer from a surface of an image-delivering member.
