Embodiment 1

[0035] First, refer to Figure 1 to Figure 16 The structure of an image forming apparatus in which the process cartridge according to the present invention is provided in this embodiment, the process cartridge also functioning as a developing cartridge including a developer accommodating container is described. Incidentally, in the following description, the rotation axis direction ( image 3 The left-right direction in ) is referred to as the longitudinal direction, and the image bearing member is used to form an electrostatic latent image on the surface of the photosensitive drum 62 .

[0036] Also, refer to the image 3 In the longitudinal direction of the photosensitive drum 62 shown as the left-right direction, the side of the photosensitive drum 62 that receives the driving force from the main assembly of the image forming apparatus A ( image 3 The right side in ) is called the driving side ( Figure 4 The driving force receiving portion 63a side shown in ), and the ...

Embodiment 2

[0139] Next, refer to Figure 9 , will describe an image forming apparatus according to the present invention in the configuration of this embodiment, in which a process cartridge also functions as a developing cartridge, the process cartridge including a developer accommodating container. Incidentally, constituent elements similar to those in Embodiment 1 described above are denoted by the same reference numerals or symbols, and description thereof will be omitted.

[0140] In Example 1, such as Figure 7 As shown, an example is described in which the auxiliary unsealing member 100 and the rotatable member 45 as the unsealing member are provided inside the toner chamber 29 . In this example, if Figure 9 As shown, an auxiliary unsealing member 100 and a rotatable member 45 as an unsealing member are provided outside the toner chamber 29 and inside the toner supply chamber 28 .

[0141] Figure 9 is a perspective view showing a state when peeling off of the sealing portion...

Embodiment 3

[0147] Next, refer to Figure 10 , the image forming apparatus according to the present invention in the configuration of this embodiment in which the process cartridge also functions as a developing cartridge including a developer accommodating container will be described. Incidentally, configuration elements similar to those of the above-described embodiment are denoted by the same reference numerals or symbols, and descriptions thereof will be omitted.

[0148] In the above-described embodiments, a configuration is applied in which the toner T is directly accommodated in the developing container. In the present embodiment, a configuration is applied in which a flexible container 300 formed of a flexible material is provided inside the developing container 23 and the toner T is accommodated in the flexible container 300 . Also, the flexible container 300 is provided with the toner supply port 27 as an opening on the side facing the toner supply chamber 28, and is provided f...

Abstract

The present invention relates to a developer accommodating container, a developing cartridge, a process cartridge and an image forming apparatus. The developer accommodating container for accommodating the developer includes: a toner sealing member for releasably sealing an opening of the developer accommodating container; an unsealing member connected to an end portion of the toner sealing member and used for unsealing the opening by moving at least a portion of the toner sealing member; and an auxiliary unsealing member for assisting unsealing by changing the pulling direction of the toner sealing member by the unsealing member. The auxiliary unsealing member includes a shaft portion or a projecting portion. The shaft portion or the protruding portion extends along the longitudinal direction of the developer accommodating container.

Description

technical field [0001] The present invention relates to a developer accommodating container, a developing cartridge, and a process cartridge to be set in an image forming apparatus, and to the image forming apparatus. Background technique [0002] As a printer, copier, facsimile machine, etc., an image forming apparatus that forms an image on a sheet by using an electrophotographic image forming type is used. [0003] Here, the process cartridge refers to a process cartridge prepared by integrally assembling a photosensitive drum and at least one of a charging device, a developing device, and a cleaning device as process members into a cartridge. Then, the process cartridge is detachably mounted in the main assembly of the image forming apparatus. [0004] An image forming apparatus using an electrophotographic image forming type forms an electrostatic latent image by selectively exposing a photosensitive drum whose surface is uniformly charged by a charging device accordin...
