[0144] Next, the characteristic configuration of the copying machine according to this embodiment will be described.

[0145] exist Figure 10 Among them, the toner bottle 33 as the storage portion is provided with a cap claw hook portion 306 , a container rotation gear 301 , and a suction portion 304 at the front end portion as one end portion in the direction of the rotation axis. The front end as Figure 6 As shown, it is accommodated in the container front end cap 34 as a holding part, and is rotatably held.

[0146] In a partial area in the circumferential direction of the outer peripheral surface of the pumping portion 304, a protruding portion 304g protruding from the outer peripheral surface (refer to Figure 19 ). The revolution radius of the protruding portion 304 g around the rotation axis of the toner bottle 33 is larger than the radius of the container rotation gear 301 .

[0168] Next, an example in which further characteristic configurations are added to the copying machine according to the present embodiment will be described. Hereinafter, unless otherwise specified, the configuration of the copying machine according to the embodiment is the same as that of the above-mentioned embodiment.

[0169] Figure 24 It is a cross-sectional view showing the installation cover 608 of the toner replenishing device according to the present embodiment and the front end portion of the toner storage container 32 accommodated in the installation cover. In the toner replenishing device according to the present embodiment, the following inclined protruding portion 304g2 is provided on the outer peripheral surface of the suction portion 304 of the toner bottle 33 . That is, as the direction of rotation of the toner bottle 33 shown by the arrow A goes backward, the inclined protrusion 304g2 departs from the above-mentioned axis of rotation (from the center of ro...

Abstract

The present invention relates to a powder storage container and an image forming apparatus. The powder storage container includes: a rotatable storage part for storing powder; a conveyor for transporting the powder stored in the storage part from the other end side in the direction of the rotation axis to one end side; and the container opening is moved to The powder on one end side is discharged to the outside; a protruding portion is disposed on a part of the outer peripheral surface of the accommodating portion and protrudes in the radial direction from the outer peripheral surface of the accommodating portion; and an opposing member is disposed so as to be in contact with the outer periphery of the accommodating portion. The protruding portion is configured to contact the opposing member as the receiving portion rotates. It can break up powder agglomerates without causing the storage part to make large eccentric movements.

Description

technical field [0001] The present invention relates to a powder container (powder container), which includes a storage part for storing powder, and a holding part that receives one end of the storage part in the direction of the rotation axis into itself and holds it rotatably, and stores the powder in the storage part It is transported from the other end side to one end side in the direction of the rotation axis. Also, the present invention relates to a powder supply device and an image forming device using the powder storage container. Background technique [0002] As such a powder supply device, the powder supply device described in Patent Document 1 is known. The toner storage container as a powder storage container of this powder supply device includes a toner bottle as a storage portion for storing toner, and a toner bottle as a rotatable holder for receiving the front end of the toner bottle into itself. The front end cover of the holding part. A bottle gear is pr...
