The developer supply container contains developer such as toner, which can flow out from the developer supply container and develops the electrostatic latent image formed on the image processing unit to form a visible image on media such as paper.
(19) Referring to
(20) In the embodiment, the cylinder 11 is closed at the end away from the housing 20, but an outlet is arranged at the end which closes to the housing 20, further, a sleeve 13 is provided at the end of the cylinder 11 close to housing 10, and preferably, the sleeve 13 is fitted at the circumferentially outer side of the open end of the cylinder 11. Referring to
(21) Further, two clamping blocks 15 are provided on the inner surface of the sleeve 13, and stress plates are provided on the outer surface of the circumferential wall of the open end of the cylinder 11, stress plates are inserted into clamping blocks 15, when the sleeve 13 rotates, the cylinder 11 will rotate synchronously with the sleeve 13.
(22) A feeding component 40 is provided in the accommodating cylinder 10, specifically, the feeding component 40 is a stirring frame, and two fixed pieces 43 are provided at one end of the feeding component 40, the inner surface of the cylinder 11 is provided two clamping blocks, and fixed pieces 43 are clamped in the clamping blocks on the inner wall of the cylinder 11. When the cylinder 11 rotates, the feeding component 40 will rotate synchronously with the cylinder 11. Thus, the sleeve 13, the cylinder 11, and the feeding component 40 will rotate synchronously, i.e., the rotation speed and the rotation direction are the same.
(23) The housing 20 is provided at one end of the accommodating cylinder 10, but the housing 20 does not follow the rotation of the accommodating cylinder 10. The external cover 18 is fastened to one side of the housing 20. Referring to
(24) The gate 35 can move relative to the housing 20, thus, fasteners 36 are provided on the two sides of the gate 35, on the two sides of the housing 20 is provided spouts, fasteners 36 can slide in the spouts. Before the developer supply container has arranged into the electrophotography imaging device, the powder feeding outlet 37 does not overlap with the powder outlet 24, i.e., the powder feeding outlet 37 does not directly face the powder outlet 24, so that developer can be prevented from flow out. After the developer supply container has arranged into the electrophotography imaging apparatus, one of the drive components of the electrophotography imaging apparatus will drive the gate 35 to move and make the powder feeding outlet 36 directly face the powder outlet 24, as seen in
(25) As the developer is transferred to the housing 20 by the feeding component 40, the developer is easy to accumulate at the powder outlet 24, which may lead to a poor supply of the developer. Thus, a stirring device is provided inside the housing in the embodiment, the developer entering the housing 20 is stirred sufficiently by the sufficient device so that developer can pass through the powder outlet 24 and the powder feeding outlet 37 smoothly.
(26) Referring to
(27) The transmission component 60 comprising a driving gear 61 and a driven gear 63, and as shown in

It is understood that the rotating shaft 66 in the embodiment is a special rotating shaft component.
(29) In the embodiment, the drive gear 60 is driven to rotate by the feeding component 40. Referring to
(30) At the end of the plate body 41 which is away from fixed blades 43 is provided a shaft hole 46, inside the shaft hole 46 is provided a spline. Further, the gear holder 51 is mounted to one end of the housing 20. And the bottom wall of the gear holder 51 is provided a shaft hole 52, the rotating shaft 62 of the driving gear 61 passes through the shaft hole 52 and inserted into the shaft hole 46. As seen in
(31) In the embodiment, the rotation direction of the driving gear 61 is the same as the rotation direction of the feeding component 40, but the rotation direction of the driven gear 65 is opposite to the rotation direction of the feeding component 40, in this way, the rotation direction of the driven gear 65 is the same as the rotation direction of feeding component 40, i.e., the rotation direction of the elastic blade 67 is the same as the rotation direction of the feeding component 40. Preferably, the rotation speed ratio of the stirring device 64 and the feeding component 40 is between 4:1 and 5:1, i.e., for each rotation of the feeding component 40, the stirring device 64 rotates 4 to 5 rotations, furthermore, the rotation speed ratio of the stirring device 64 and the feeding component is 4.5:1, i.e., for each rotation of the feeding component 40, the stirring device rotates 4.5 rotations.
(32) In the embodiment, the elastic blade 67 is one piece, and the middle of the lengthwise direction of the elastic blade 67 is fixed on the shaft rotating 66, i.e., the middle of the elastic blade 67 is a fixed end, and the two ends of the lengthwise direction are free ends. The elastic blade 67 can be elastically deformed when it rotates, and enlarged the stirring force that applied to the developer, which makes the developer is fully stirred.
(33) In addition, at the end of the feeding component 40 which is away from the fixed piece 43 is provided two feeding portions 45, both of these feeding portions 45 are quarter circles, and both of these feeding portions 45 are provided on the outer circumferential wall of the shaft hole 46.
(34) Referring to
(35) The circumferential wall 21 of the housing 20 has enclosed an accommodating cavity 25, both ends of accommodating cavity 25 are opened along the axial direction of the cylinder 10, the gear holder 51 is arranged in one open end of the accommodating cavity 25. One end of the feeding component 40 can be arranged in the accommodating cavity 25, thus, the developer will be transferred into the accommodating cavity 25. In order to prevent leakage of the developer inside the accommodating cavity 25 from the gap between the housing 20 and the gear holder 51, as seen in
(36) On the radially outer side of the circumferential wall 21 of the housing 20 is provided three threaded holes 22, as shown in
