Abstract
A developer cartridge includes a cylindrical member in which developer containing at least toner is stocked, a supply port opened in the cylindrical member, and a spiral feeding member which is freely rotatably disposed in the cylindrical member and rotated to feed the developer stocked in the cylindrical member to the supply port. The feeding member is mounted in the cylindrical member after developer is filled in the cylindrical member.
Claims18
A developer cartridge comprising:
- a cylindrical member in which developer containing at least toner is stocked;
- a supply port opened in the cylindrical member;
- and
- a spiral feeding member which is freely rotatably disposed in the cylindrical member, the feeding member being rotated to feed the developer stocked in the cylindrical member to the supply port,
- wherein the feeding member is mounted in the cylindrical member after the developer is filled in the cylindrical member.
A developer cartridge comprising:
- a cylindrical member in which developer containing at least toner is stocked;
- a supply port opened in the cylindrical member;
- a spiral feeding member which is freely rotatably disposed in the cylindrical member, the feeding member being rotated to feed the developer stocked in the cylindrical member to the supply port;
- and
- a cap member for sealing an open end portion of the cylindrical member,
- wherein the feeding member is freely rotatably attached to the cap member at one end portion thereof, and pivotally supported in the cylindrical member through a shaft member and a bearing member, from which any developer trapped is automatically removed, at the other end portion opposite to the cap member.
A method of manufacturing a developer cartridge comprising a cylindrical member in which developer containing at least toner is stocked, a supply port opened in the cylindrical member, and a spiral feeding member which is freely rotatably disposed in the cylindrical member, the feeding member being rotated to feed the developer stocked in the cylindrical member to the supply port, the method comprising the steps of:
- filling the developer in the cylindrical member;
- and
- mounting the feeding member in the cylindrical member.
