Abstract

Blade cleaner apparatus for removing residual toner from a charge-retentive surface including a cleaner housing 9 having a cleaning blade 10 disposed therein adjacent the top thereof The apparatus is characterized by improved structure for reducing the escape of toner particles from the housing. Seals 12 (only one shown) are disposed between the blade ends and side frame members 14. The seals block the flow of toner laden air past the ends of the cleaning blade. Thus, the flow of toner laden air is redirected to behind the blade which allows toner to separate from the air prior to its exodus from the cleaner housing area.

BLADE CLEANER APPARATUS FOR REMOVING TONER FROlLl A CHARGE-RENTENTIVE SURFACE (Cont'd)

Blade cleaner apparatus for removing residual toner from a charge-retentive surface including a cleaner housing 9 having a cleaning blade 10 disposed therein adjacent the top thereof The apparatus is characterized by improved structure for reducing the escape of toner particles from the housing. Seals 12 (only one shown) are disposed between the blade ends and side frame members 14. The seals block the flow of toner laden air past the ends of the cleaning blade. Thus, the flow of toner laden air is redirected to behind the blade which allows toner to separate from the air prior to its exodus from the cleaner housing area.

As can be seen from Figures 1 and 2, one of the pair of end seals 12 is positioned intermediate the end of the blade 10 and one of a pair of side frames 14. As illustrated, one of the pair of seals is secured to the side frame 14 such that the free ends 16 of the fibers receive the ends of the blade 10 and blade holder 18. The seals serve to block air flow created by a photoreceptor 20 and cause the toner laden air to be redirected behind the blade 10. As a result of such redirection, the velocity of the air is significantly lowered thereby enabling the toner contained therein to fall out of the air...
