| 20090087226 | Developer Cartridge, Developing Device, Process Cartridge and Image Forming Apparatus - A developer cartridge includes a housing attachable to and detachable from a developing device and accommodating developer and an agitator agitating the developer in the housing and supplying the developer to the developing device through a supply opening of the housing. The agitator includes a rotation shaft, a support plate, a delivery agitation blade supported by the support plate and passing through a position opposing the supply opening along an inner surface of the housing by rotation of the rotation shaft, an entire width of a first end portion of the delivery agitation blade being supported by a distal end portion of the support plate, and an oblique agitation blade erected from a surface of the support plate and oblique to the rotation shaft in order to move the developer in an axial direction of the rotation shaft toward the supply opening. | 2009-04-02 |
| 20090087227 | Developer Cartridge, Developing Device, and Process Cartridge - A developer cartridge includes a housing for accommodating developer, a rotation shaft rotatably supported by the housing and passing across an inside of the housing, a supply opening formed in a wall of the housing opposite in a diameter direction of the rotation shaft, a return opening formed in a wall of the housing at a position displaced from the supply opening in an axial direction of the rotation shaft, a first agitation blade supported by the rotation shaft and passing through a position opposite the return opening along an inner surface of the housing from an above to a below of the position opposite the return opening along with a rotation of the rotation shaft, and a second agitation blade supported by the rotation shaft and passing through a position opposite the supply opening along an inner surface of the housing. | 2009-04-02 |
| 20090087228 | Developer transportation device and image forming apparatus - A developer transportation device includes a storage portion for storing developer; a transportation member formed of an elastic material and disposed in the storage portion to be freely rotatable for transporting the developer upon rotating; and a rotation transmission member for transmitting a rotation to the transportation member. The transportation member may be provided with an abutting portion abutting against a wall portion of the storage portion when the transportation member rotates. | 2009-04-02 |
