<P>PROBLEM TO BE SOLVED: To provide a developer cartridge, capable of preventing unnecessary deformation of a seal member which is provided on a second frame adapted to open and close an opening by a relative movement between a first frame and the second frame in order to prevent leak of developer from the opening, and a developing unit and an image forming apparatus installed with the developer cartridge. <P>SOLUTION: A toner seal 92 is disposed in a position different from a position in which it overlaps an outer casing 82 as viewed from a toner passing direction X (substantially longitudinally) in a state where an inside passing port 89 is opened (a position in which it does not overlap the outer casing 82). Namely, since the toner seal 92 does not contact with the outer casing 82 in the state where the inside passing port 89 is opened, the toner seal 92 can be prevented from being deformed by the contact with the outer casing 82. <P>COPYRIGHT: (C)2010,JPO&INPIT |
