Toner reservoir for photocopier - has adjustable endwall to regulate toner thickness flow and profiled lip acting as scraper

摘要

A toner reservoir for a photocopier has a sloping wall at one side and a vertical wall at the other, set between parallel and vertical sidewalls. The vertical end wall is adjustable to regulate the thickness of toner powder onto the magnetic applicator roller. The bottom edge of the vertical wall has a profiled lip, with an edge to scrape the toner coating on the roller to a set thickness. The bottom edge of the sloping wall is turned up to form a defining slot w.r.t. the vertical wall.
