Problems solved by technology
[0008] However, if the supporting portion supporting the above-mentioned screw shaft protrudes outward from the side wall of the housing, it is difficult to use the metal model to form structural parts such as gripping parts on the side wall of the housing due to the structure of the metal model. The design freedom of the outer side of the wall is sometimes reduced
[0009] In addition, if the above-mentioned support portion and the end portion of the screw shaft are both arranged on the outside of the side wall of the housing, the support portion may place a large restriction on the arrangement of the components on the side of the device body.
[0010] However, if the support portion is arranged on the inner side of the side wall of the housing, since the toner accumulated around the support portion will not be conveyed by the conveying blades of the spiral portion, toner tends to occur around the support portion. agglutination problem

Embodiment Construction
[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the present invention is not limited to the following embodiments.
[0027]
[0028] figure 1 It is a cross-sectional view showing a schematic configuration of a laser printer 1 serving as an image forming apparatus in this embodiment.
[0029] like figure 1 As shown, the laser printer 1 has an apparatus main body 2 and a toner cartridge 21 as a toner container, wherein the toner cartridge 21 is installed in the apparatus main body 2 and can be detached.
[0030] The device main body 2 has a manual paper feeding unit 6 , a cassette paper feeding unit 7 , an image forming unit 8 , a fixing unit 9 , and a paper output unit 10 . In this way, the laser printer 1 conveys the paper along the conveyance path L in the apparatus main body 2 and forms an image on the paper based on image data transmitted from a not-shown terminal device or the like.

The invention provides a toner container and an image forming device having the same. The toner container comprises: a toner supply unit provided in a housing (31) for supplying toner to a device body; a screw (50) having a screw shaft (51) driven rotationally inside the housing (31), and a conveyance blade (52) formed on the screw shaft (51) for conveying toner to a toner supply unit by rotating along with the screw shaft (51); and a support section (53) which is arranged further inside the housing (31) than the side wall (31a) of the housing (31) to support the end of the screw shaft (51), and has a portion of the conveyance blade (52) provided therearound.
Description
technical field [0001] The present invention relates to a toner container and an image forming apparatus having the toner container. Background technique [0002] For example, as disclosed in Patent Document 1, an image forming apparatus such as a laser printer has a toner cartridge as a toner container mounted in a main body of the apparatus. An image forming unit having a developing unit is provided in the apparatus main body. [0003] The toner cartridge has a housing for storing toner as a developer. The housing is provided with a toner supply unit for supplying toner to the developing unit of the apparatus main body. In addition, a spiral part and a stirring mechanism are provided inside the casing, wherein the spiral part is used to convey the toner to the toner supply part, and the stirring mechanism is used to stir the toner. [0004] The stirring mechanism has a shaft and a stirring sheet, wherein the shaft is driven to rotate inside the casing; the stirring shee...
