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