<P>PROBLEM TO BE SOLVED: To provide a developing apparatus capable of preventing the metal mold structure of a housing from being complicated, and capable of achieving a low-cost fabrication. <P>SOLUTION: The developing apparatus includes: a developing part 630 including a developing roller 601, a supply roller 602 and an agitating member 603; a toner hopper 640 disposed above the developing part; an agitating member 604 disposed in the toner hopper; a partitioning member 610A with an opening, disposed between the developing part and the toner hopper; and a recovered developer storage and forming part 603B for forming the storage space for the recovered toner at a specified distance from the supply roller so that the recovered toner recovered from the developing roller by the supply roller may be moved close to the agitating member 603 with the flow of the developer in response to the rotation of the supply roller. A pre-assemblage component 610, where the partitioning member 610A, the recovered developer storage and forming part 610B and bearing parts 610C and 610D for supporting the agitating members 603 and 604 are integrally formed, is assembled with the housing 650. <P>COPYRIGHT: (C)2008,JPO&INPIT |
