ABSTRACT:
A cleaner unit is disclosed with a rubbery elastic cleaning blade. The blade extends horizontally from an upright base member, where the cleaning edge contacts a vertically downward passing photoconductive surface such that toner scraped from the surface travels over the upper face of the blade without causing a toner cloud. The removed toner is guided over this upper surface of the cleaning blade through the use of seals along the cleaning blade edge and outside the image carrying area of the photoconductive surface, as well as through the use of toner guiding grooves between the end seals.
