Abstract
A magnetic toner developing system has a hopper feeding magnetic toner to a magnetic roller brush positioned over a non-magnetic guide that supports a sheet in its passage through a development zone. A plurality of magnets are mounted beneath the guide and restrain any toner on the underside of the sheet from being carried away from the development zone. The stronger magnetic field of the developer brush attracts the restrained toner as the sheet is transported out of the development zone.
