The developer supply component comprises a rotary shaft and a developer supply plate, wherein the rotary shaft is a crank shaft; and one end of the developer supply plate is provided with a part which is sleeved at the periphery of a crank throw neck of the crank shaft to make the developer supply plate and the crank shaft connected in a movable mode.
Description
Technical field
The present invention relates to the Delevoping cartridge that transports the developer conveying component of developer in a kind of Delevoping cartridge used for electronic photography image forming apparatus and there is this developer conveying component.
Background technology
In electrophotographic image forming, conventionally use dismountable Delevoping cartridge to provide carbon dust for it, with by the latent electrostatic image developing on photosensitive-member, be then transferred on the media such as paper and form visual picture.Publication number is that the Chinese invention patent application of CN101241336A discloses a kind of Delevoping cartridge, it comprises pancake box body, in box body, there is the developer-accommodating chamber of receiving photographic developer, be subject to the restriction of its inner space, the mechanism that transports developer in developer-accommodating chamber one has the developer feeding plate of flow orifice, its one end connects on developer-accommodating cavity wall by spring, the other end has jut and can contact with the turning axle in developer-accommodating chamber, after contacting with the jut of developer feeding plate, turning axle promotes the motion of developer feeding plate along continuous straight runs, after turning axle and developer feeding plate disengage, developer feeding plate returns back to original position under spring force effect.Along with the rotation of turning axle, developer feeding plate is to-and-fro movement in the horizontal direction, carries out transporting of developer by its flow orifice.
But this kind of developer feeding plate along continuous straight runs motion, flow orifice on it very easily stops up, thereby reduce transport developer ability, in addition, developer easily bonds between developer feeding plate and developer-accommodating chamber, the motion of developer feeding plate is formed and hindered, even make developer feeding plate stop motion, developer conveying efficiency is poor.When the developer in Delevoping cartridge is shown while being finished by electrophotographic image forming, residual more developer in fact also in developer-accommodating chamber, causes the waste of resource and the increase of use cost.
Summary of the invention
Fundamental purpose of the present invention is to provide the developer feeding member that a kind of developer conveying efficiency is high;
Another object of the present invention is to provide a kind of Delevoping cartridge with above-mentioned developer feeding member.
For realizing above-mentioned fundamental purpose, developer feeding member provided by the invention comprises turning axle and developer feeding plate.Wherein, turning axle is bent axle, and one end of developer feeding plate has and is enclosed within the part that the crank throw neck periphery of described bent axle is movably connected described developer feeding plate and described bent axle.
Be movably connected by one end of developer feeding plate and the crank throw neck of bent axle, developer feeding plate does not rotate with bent axle, but the rotation of bent axle can cause developer feeding plate vertically and the motion of horizontal direction.Compared with scheme in background technology, developer feeding plate can move along both direction, and the inevitable rotation campaign because of bent axle of development feeding plate, transports efficiency and improves, and developer residual quantity is low.
More concrete scheme is that developer feeding plate has polylith, and bent axle is provided with at the crank throw neck that radially departs from rotating shaft center with different directions, and same direction departs from the crank throw neck of rotating shaft center corresponding to a developer feeding plate.A bent axle drives the motion of polylith developer feeding plate, further increases the ability of transporting developer.
Another more concrete scheme is that developer feeding plate has polylith, and described bent axle also should have many mutually.Many bent axles drive polylith developer feeding plate, to increase the ability of transporting developer.
Another more concrete scheme is that on developer feeding plate, the direction along parallel described turning axle is provided with fin.In developer feeding plate motion process, fin can be dialled and move developer, further increases the ability of transporting developer of developer feeding plate.
Scheme is that fin is provided with perpendicular to described rotation axial disconnection mouthful more specifically.When developer feeding plate motion, developer can flow from disconnected opening part, and developer is difficult for piling up and bonding.
Delevoping cartridge provided by the invention comprises the box body that is provided with developer-accommodating chamber, developer-accommodating chamber has the outwards opening of output of developer, developer roll can be rotatably set in opening part, in developer-accommodating chamber, be provided with the developer feeding member that comprises turning axle and developer feeding plate, turning axle is bent axle, and one end of developer feeding plate has and is enclosed within the part that the crank throw neck periphery of bent axle is movably connected developer feeding plate and bent axle.
Be movably connected by one end of developer feeding plate and the crank throw neck of bent axle, developer feeding plate does not rotate with the rotation of bent axle, but the rotation of bent axle can cause developer feeding plate in developer-accommodating chamber vertically and the motion of horizontal direction, thereby cause developer to move to developer roll.Compared with scheme in background technology, developer feeding plate can move along both direction, and the inevitable rotation campaign because of bent axle of development feeding plate, transports efficiency and improves, and developer residual quantity is low.
