Claims12
A developer container comprising:
- a main body container for containing a magnetic developer;
- a rotary member rotating in contact with the magnetic developer;
- and
- a seal member for preventing the magnetic developer from leaking at an end in a direction of a rotating shaft of said rotary member,
- wherein said seal member includes an elastic contact portion being in contact with said rotary member for sealing the magnetic developer, and a magnetized magnetic body for sealing the magnetic developer magnetically without being in contact with said rotary member, wherein said elastic contact portion and said magnetized magnetic body are integrally formed, wherein said magnetized magnetic body is provided so as to extend from an inner side to an outer side of said elastic contact portion in the direction of said rotating shaft, and wherein an inner side portion of said elastic contact portion of said magnetized magnetic body has a force attracting the developer magnetically.
