<P>PROBLEM TO BE SOLVED: To provide a seal member for toner which satisfies both a stable sealing property and good wear resistance and to provide a toner cartridge using the seal member. <P>SOLUTION: The sealing member 23 includes; an outer cylinder part 23a for forming an outer periphery surface 23c, an inner flange part 23b provided on an inner surface of the outer cylinder part 23a slanted toward inner side of a toner container, and an annular projection 32 provided in a position more to an outer side of the toner container than a base of the inner flange part 23b on the inner surface of the outer cylinder part 23a. An annular groove 23e is formed between the inner surface of the outer cylinder part 23a and an outer surface of the inner flange part 23b. Projecting height d1 from the inner surface of the outer cylinder part 23a on a top part 31 of the inner flange part 23b is greater than projecting height d2 from the inner surface of the outer cylinder part 23a of the annular projection 32. <P>COPYRIGHT: (C)2008,JPO&INPIT |
