Abstract
A device for mounting a magnetic roller which is disposed in a developing unit of a copying apparatus to apply toner to a drum at a given thickness. The device includes a toner box composed of two separate boxes which are joined to each other by an adhesive tape, and coil springs extending between the boxes. The second box is provided with protruding guide portions for receiving and supporting the magnetic roller therein to prevent an overflow of toner from the toner box.
