[0035]

[0036] figure 1 Shown is a schematic diagram of a configuration example of the image forming apparatus 100 according to the first embodiment.

[0037] like figure 1 As shown, the image forming apparatus 100 includes a photosensitive drum 2 , a charging roller 3 , a developing device 4 , a cleaning blade 5 , an exposure device 7 , a transfer belt 10 , a secondary transfer roller 12 , a fixing device 16 and the like. In addition, although the image forming apparatus 100 according to the first embodiment is a tandem type color printer in which a plurality of developing units including the developing devices 4 for forming toner images of different colors are arranged in parallel, can also be in figure 1 In the configuration shown, a color multifunction machine combined with a scanner or the like, or a monochrome printer or a monochrome multifunction machine composed of a single developing unit that forms a black image.

[0038] Next, the image forming operation in th...

[0068] Next, a second embodiment will be described. Note that the description of the same components as those in the first embodiment will be omitted.

[0069] Image 6 Shown is an example of a schematic cross-section of the toner container 50 according to the second embodiment.

[0070] like Image 6 As shown, the toner container 50 according to the second embodiment includes a rod-shaped member 51, a stretchable portion 52, a discharge port 53, a supporting member 54, and the like.

[0071] The rod-like member 51 is mounted toward the discharge port 53 from the inner surface on the opposite side of the discharge port 53 of the toner container 50 in the telescopic direction B, and is rotatably provided with a helical fin 57 on the outer peripheral surface of the rotation shaft 56. .

[0072] The supporting member 54 is fixedly provided in the side wall of the toner container 50 , and supports the rod-shaped member 51 after having a shape along a part of the spiral fin 57 ...

Abstract

The invention provides a developer container which has a simple structure and can supply developer without blockage or splashing of the developer, a development device, a process unit, and an image forming apparatus. The developer container contains the developer inside and stretches and retracts in one direction. The developer container comprises a discharging port which is arranged on one side of the stretching and retracting direction and discharges the developer and a rod component which is arranged to face the discharging port from the inner surface of the other side of the stretching and retracting direction and moves in the stretching and retracting direction along with the stretching and retracting of the developer container.

Description

technical field [0001] The present invention relates to a developer container, a developing device, a process cartridge and an image forming device. Background technique [0002] Some developing devices of image forming apparatuses employing an electrophotographic system include a toner container in which toner serving as a developer is previously sealed inside. A developing device having a toner container is supplied with toner by peeling off a sealing member or the like provided in the toner container for sealing the toner at the beginning of use, and is used in an image forming apparatus. for the formation of toner images. [0003] Here, in the developing unit in which the developing unit and the toner container are integrated, when the toner supplied to the developing unit is exhausted (toner end), the developing unit including the developing unit is used as a unit. to exchange for new ones. However, such exchange in units of developing units is performed when there a...
