A high load low load cleaning blade assembly provided for cleaning a toner
image bearing surface includes a blade member having a first edge mounted
to a frame, a second and opposite edge for contacting and loading against
the toner image bearing surface, and a blade width connecting the first
edge to the second edge. The high load low load blade assembly also
includes a blade holder for holding and loading the blade member against
the moving toner image bearing surface. The blade holder includes a
frame, and a blade loading plate operatively connected to the frame and
extending from the frame towards the second edge of the blade member for
stiffening the blade width and determining a resulting blade loading
force of each portion of the second edge against regions of the toner
image bearing surface. The blade loading plate includes a central segment
having a first plate width for stiffening the central portion of the
blade member, and end segments, each having a second plate width less
than the first plate width, for stiffening end portions of the blade
member, thereby resulting in a second edge having a high load central
portion and low load end portions.
