Abstract
An elongated toner box extending in a horizontal direction has a cylindrical portion where a toner discharge port is formed. A wrapping member serving as a shutter is rotatably disposed over the cylindrical portion for selectively shutting off the toner discharge port. The wrapping member has a circular shape concentrical with the cylindrical portion. A developing case is provided to which the toner box is detachably installable. The developing case has a wall confronting the toner box, and a toner inlet port is formed at the wall. A toner inlet shutter is slidably movably supported to the partition wall. When the wrapping member opens and closes the toner discharge port, the wrapping member is positioned close to the outer surface of the toner box and does not largely protrude from the toner box. Further, the discharge port shutter and the inlet port shutter are movable in interlocking relation with each other.
