no. 1 approach

[0096] First, refer to figure 1 and figure 2 , Describe the overall structure and operation of the image forming apparatus. figure 1 It is a structural diagram showing a printer as an image forming apparatus, figure 2 It is an enlarged view showing the imaging part.

[0097] Such as figure 1 As shown, opposite to the intermediate transfer belt 11 of the intermediate transfer unit 10, image forming units 6Y, 6M, 6C, 6Bk corresponding to each color (yellow, magenta, cyan, and black) are arranged side by side. In addition, the four image forming units 6Y, 6M, 6C, and 6Bk provided in the main body 100 of the apparatus are basically the same in structure except for the toner used in the image forming process. figure 2 The letter marks (Y, M, C, Bk) in the image forming unit 6, the photosensitive drum 1, and the primary transfer bias roller 9 are omitted in the illustration.

[0098] Reference figure 2 The imaging unit 6 is composed of a photosensitive drum 1 as an image carrier, a ch...

no. 2 approach

[0209] Reference Figure 27 ~ Figure 33 , The second embodiment will be described in detail. In the second embodiment, the structure not specifically described is the same as that of the first embodiment.

[0210] In the prior art, there is known a developer supply device (see Japanese Patent Application Laid-Open No. 2005-91879). The developer supply device inserts a nozzle in a flexible container containing toner, and passes through the nozzle in the pump Under the action, the toner is sucked out and refilled to the developing device. In this toner replenishment method, as the toner is sucked out by the pump, the flexible container automatically reduces its volume. Then, in a state where there is almost no toner in the container, the container is in a squashed state, so it is possible to reduce the cost required for collection, transportation, and reuse of the used container. Furthermore, since the volume of the container is reduced according to the remaining toner amount in ...

no. 3 approach

[0241] Reference Figure 34 ~ Figure 38 , The third embodiment will be described in detail. In the third embodiment, the structure that is not particularly explained is the same structure as the first embodiment. According to Figure 34 ~ Figure 38 The specific structure of the vibration applying mechanism and the fixing portion provided with the vibration applying mechanism will be described.

[0242] Figure 34 Is a cross-sectional view of the fixed portion 63, Figure 35 Is a perspective view of the vibration applying mechanism, Figure 36 versus Figure 37 It is a perspective view of the fixed part.

[0243] Such as Figure 34 As shown, the fixed portion 63 is provided with an eccentric weight 93 attached to the rotating shaft as a vibration applying mechanism. And, as Figure 35 As shown, the eccentric weight 93 is a cylindrical member protruding to both sides in the axial direction, and an insertion hole 93a for inserting the rotating shaft is formed at a position deviated f...

Abstract

According to the embodiment, a powder storage container has a powder storage portion, the powder storage portion has an opening formed at one end, powder is stored inside, and is made of a soft material; the discharge portion is provided in the opening portion. One end is fixed to the powder conveying device and is used to discharge the powder sent out from the opening to the powder conveying device; when the sending member is pressed in the direction opposite to the moving direction, the locked portion is arranged between The end on the opposite side of the opening is locked in the locking portion of the powder conveying device. In this powder storage container, the discharging member is pushed in from the outside of the powder storage portion and moved toward the opening, thereby discharging the powder from the opening.

Description

Technical field [0001] The present invention relates to a powder storage container containing powder inside, a powder conveying device that conveys the powder contained in the powder storage container to a discharge portion, and a powder storage container and the powder conveying device Image forming device. Background technique [0002] In electrophotographic image forming apparatuses such as copiers, printers, facsimile machines, or multifunction machines equipped with these functions, a developer called a toner or a carrier is generally used, and a toner image is formed by the developer to form an image. This type of image forming apparatus consumes toner while forming an image. Therefore, a toner cartridge containing toner is usually installed in the image forming apparatus. If the toner in the toner cartridge runs out, replace it. A new toner cartridge to replenish toner. [0003] In the toner replenishment method using the above-mentioned toner cartridge, in order to reduce...
