Problems solved by technology

Therefore, the toner outside both ends of the toner conveying screw cannot be sent to the supply opening, and it is difficult to send the toner without remaining in the container.
[0007] In addition, in order to dispose the toner conveying screw near the center in the longitudinal direction of the container, the toner conveying screw must be axially supported in the container, so there is a disadvantage that the state of the axial support is unstable.
In addition, in order to assemble the toner conveying screw in the container, after the toner conveying screw is inserted into the container, a designated bearing member must be pivotally supported, so there is also a problem of poor assembly workability.

[0200] FIG. 19 is a partially cutaway exploded perspective view showing a toner container 20A of the second embodiment. FIG. 20 is a partially cutaway assembled perspective view of the toner container 20A viewed obliquely from above on the front side, and FIG. 21 is a perspective view of the toner container 20A viewed obliquely below from the rear side. In these figures, the same parts as those of the toner container 20 of the first embodiment are assigned the same reference numerals. In order to simplify the description, descriptions of the same parts are omitted or simplified.

[0201] The toner storage 20A includes: a container 30A for storing toner, an agitation device 40A for agitating the toner in the container 30A, a conveying member 50 for conveying the toner in the container 30A, a setting providing Or the shutter cylinder 60A that does not supply toner and the shield cover 70A that covers the left side plate 314 . The container 30A includes a container body 31A and...

Abstract

The present invention provides a toner container and developer replenishing device. Said toner container for containing toner includes: a container having a toner discharge hole for containing toner; a toner conveyance screw for conveying the toner within the container toward the toner discharge hole; and a shutter cylinder including a peripheral wall formed with a toner discharge opening at a position corresponding to the toner discharge opening. The toner conveyance screw is rotatable supported at one end thereof by a bearing within the shutter cylinder. The shutter cylinder is mounted to a side wall of the container in a rotation free manner. Thereby, the stability state of the toner conveyance screw can be realized, and the operability of the toner conveyance screw to container assembly can be improved furthermore.

Description

technical field [0001] The present invention relates to a toner container and a developer replenishing device detachably mounted on an image forming apparatus such as a copier, a printer, and a facsimile for replenishing toner to a developing device installed in the image forming apparatus. Background technique [0002] Currently, a toner container as described in Japanese Patent Laid-Open Publication No. 2003-280344 is known to the public. The toner container is detachably mounted on the developing device in order to replenish toner to the developing device installed in the main body of the image forming apparatus. When it is low, replenish toner to the developing device. [0003] This toner storage includes: a box-shaped container filled with toner inside; a toner conveying screw provided at the bottom of the container to pay out the toner inside and replenish it into the developing device; a driving force transmitting part for transmitting the driving force from the dri...
