Abstract

Blade cleaning has been an established method for removing toner from a photoreceptor for many years. The drawback to cleaning with an elastomeric blade is that the seal between blade and photoreceptor is relatively easily broken with the result that field failures occur randomly and are primarily associated with fibers under the blade, local tuckunders, etc.

MAGNETIC BLADE CLEANER Proposed Donald A. Seanor Classification

Blade cleaning has been an established method for removing toner from a photoreceptor for many years. The drawback to cleaning with an elastomeric blade is that the seal between blade and photoreceptor is relatively easily broken with the result that field failures occur randomly and are primarily associated with fibers under the blade, local tuckunders, etc.

The way to overcome the limitations of the single attempt (i.e., single blade) cleaner is to use a multiple attempt cleaner, e.g., dual blade, fiber brush, etc. Each of these methods has its own cost/function problems.

This disclosure relates to using a simple magnetic brush in the form of a magnetic blade (bar magnets) upon which a relatively stiff brush of magnetic carrier is formed as illustrated in the drawings: Figures 1 - 3 illustrate various magnet configurations contemplated.
