WIPO Patent Application WO/2007/095853
Kind Code:
A1
Abstract:
A developer cartridge for electrophotographic image-forming apparatus includes a
cylindrical inner barrel (1) for storing powder and a protective case (2). The protective
case (2) is provided on the cylindrical external wall of the inner barrel (1).
A powder supply blade (302) in the inner barrel (1) is comprised of a fixed part
(3021), a powder supply part (3022) and a powder hold part (3023). The fixed part
(3021) is fixed on the center shaft (301) of a carbon powder stirring device (3).
One end of the powder supply part (3022) is connected to the fixed part (3021),
and the other end is connected to the powder hold part (3023). On the axial cross
section of the inner barrel (1), the powder supply part (3022) forms an acute angle
with respect to the rotation direction of the carbon powder stirring device (3).
The length from the rotary shaft of the carbon powder stirring device (3) to the
end portion of the powder supply part (3022) is slightly less than radius of the
inner chamber (101). The powder hold part (3023) is represented as a chord or an
arc of the inner chamber (101) on the axial cross section of the inner barrel (1).
