<P>PROBLEM TO BE SOLVED: To provide a developing device capable of preventing the occurrence of a toner leakage even after a developing tank is repeatedly removed. <P>SOLUTION: A rotary shutter 4 is rotatably supported between a supply opening 32 formed in a toner supply device 2 and a receiving opening 33 formed in a developing tank 3. The rotary shutter 4 opens or closes the supply opening 32 in synchronism with the removal operation of the developing tank 3. The rotary shutter 4 has an open section 36 made through a roller-like body so as to extend in an axial direction and perpendicular to the axial direction. The rotary shutter 4 closes the supply opening 32 by covering the supply opening 32 with the peripheral face of the roller and opens the supply opening 32 by allowing the communication, via the open section 36, between the supply opening 32 and the receiving opening 33. <P>COPYRIGHT: (C)2008,JPO&INPIT |
