Embodiment 1

[0043] like Figure 5 Shown is a schematic structural view of the photosensitive element cartridge 1 of the present invention, the photosensitive element cartridge 1 includes a box body, and a first platen roller 12a rotatably fixed on the box body is arranged on the bottom surface of the box body, as Image 6 shown as Figure 5In the cross-sectional view at B, the first platen roller 12a contacts and presses against the second platen roller (not shown) in the image forming apparatus, wherein the second platen roller is driven by a motor (not shown) in the image forming apparatus ) to rotate under the action of the first platen roller 12a on the photosensitive element cartridge 1 to rotate synchronously, so as to transfer the paper P to the transfer assembly, that is, the photosensitive element 10 and the transfer roller 11, so that the photosensitive element 10 The toner from the electrostatic latent image on the surface is transferred to the paper. The first platen roller ...

Embodiment 2

[0048] The working principle of the first platen roller 12a of this embodiment is the same as that of the first embodiment, so it will not be described here, but its installation process and fixing method will be explained emphatically. like Figure 10 , Figure 11 and Figure 12 As shown, the two ends of the rotating steel shaft 12a2 of the first platen roller 12a are still supported and fixed by two supports, which are different from the integrated support 13 in Embodiment 1. The two supports in this embodiment are respectively one One is a fixed support, and the other is a detachable support. The structure of this support and the installation of the first platen roller 12a will be described in detail below.

[0049] like Figure 11 shown as Figure 10 Partial enlarged view of the fixed first support member 20 at C in the figure, the first support member 20 is integrally formed with the box body of the photosensitive element cartridge 1 and has a circular hole 20a, and t...

Embodiment 3

[0053] Likewise, the working principle of the first platen roller 12a of this embodiment is the same as that of the first embodiment, so it will not be described here, but its installation process and fixing method will be explained emphatically. like Figure 14 As shown, in this embodiment, the X-end and Y-end fixed support members of the first platen roller 12a rotating steel shaft are integrally formed with the photosensitive element box 1, and the support method and structure of this support member and the first A mounting method of the platen roller 12a is described in detail.

[0054] like Figure 15 Both the X end and the Y end of the supporting member are provided with supporting holes 31 for supporting and fixing the rotating steel shaft 12a2 of the first platen roller 12a. The minimum distance between the two supporting holes 31 of the supporting member is S2, and its length is less than The length S1 of the rotating steel shaft 12a2 of the first platen roller 12a,...

Abstract

The invention relates to a photosensitive element box which is installed on an image forming device in a detachable way, and comprises a box body, a first paper press roller and two supporting pieces, wherein the first paper press roller is connected with a second paper press roller of the image forming device in a pressing way when the photosensitive element box is arranged on the image forming device; and one ends of the two supporting pieces are respectively connected with rotating shafts arranged at the two ends of the first paper press roller, and the other ends are fixedly connected with the box body. The two supporting pieces are fixedly connected with the box body, and the first paper press roller is rotatablely fixed on the box body and can not freely move up and down, so that the box body is not beaten by the first paper press roller, no noise is generated, and the photosensitive element box is beneficial to transportation and use. The problems that when the photosensitive element box is transported or used, the box body of the photosensitive element box is continuously beaten by the first paper press roller which freely moves up and down, so that great disharmony is caused for the transportation, use and the like, and the use accuracy and appearance of the product are influenced can be solved.

Description

technical field [0001] The present invention relates to a photosensitive member cartridge used in an electrophotographic image forming apparatus such as a laser printer. Background technique [0002] An electrophotographic image forming device such as a laser printer is a device that uses the principle of electrophotography to form an image on an image forming medium such as paper at least through charging, exposure, development, transfer, and fixing processes. [0003] In the charging process, through the charging device, the surface of the photosensitive element such as the photosensitive drum is charged with a uniform predetermined charge by means of corona discharge; in the exposure process, the surface of the photosensitive element that has been charged with a uniform predetermined charge is selectively exposed. In the place exposed to light, due to the photosensitive characteristics of the photosensitive element, the resistance drops, so the charge on the exposed place...
