Abstract
PURPOSE:To obtain the discharging device of developer which is capable of recovering the developer efficiently and nearly perfectly by so constituting the device that a magnet and a non-magnetic sleeve are rotated integrally at the recovering of developer. CONSTITUTION:After a developing device 2 is dismounted from the body of the copying machine, an auxiliary plate 30 is mounted to the position of a doctor plade 8 and its end edge is contacted to the surface of a sleeve 4. Next, as the non-magnetic sleeve 4 is rotated in the direction opposite from the arrow b by a manual knob 24, a magnet bar 5 is integrally turned by cooperation with magnetic carrier. This results in the increased conveying power of the developer of the non-magnetic sleeve 4, enabling the developer to be scraped and recovered efficiently by the auxiliary plate 30. After recovery, the auxiliary plate 30 is removed and fresh developer is replenished by opening a replenishing cover 17, thence the developing device is mounted to the body of the copying machine. The magnetic bar 5 is latched automatically to the specified rotating position through engagement of a ratchet 26 and pawl 28.
