Abstract
A toner recovery device is provided in an electrostatic recording apparatus through the arrangement of an endless nonmagnetic belt extending about a cylinder mounted coaxially with the drum. The belt moves from the drum to an idler located at the top of a toner supply bin. A blade is provided for scraping toner from the drum into contact with the belt on the cylinder. Magnets mounted about the inside of the cylinder attract the scraped off toner to the belt when it is on the drum. The belt carries the attracted toner from off the drum to the idler in the supply bin. Toner drops from the belt into the supply bin where it is mixed with the toner already therein.
