Problems solved by technology

[0006] However, in the process cartridge of the type that connects the photoreceptor unit and the developing unit using a joint plate, the number of components increases due to the use of the joint plate, resulting in an increase in cost.
In addition, due to the use of connecting plates, it is troublesome to assemble
[0007] In the above-mentioned process cartridge of the type using a jig to connect the photoreceptor unit and the developing unit, although the dimensional accuracy between the photoreceptor drum and the developing roller after assembly is very high, the assembly work is more troublesome.

Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] figure 1 It is a longitudinal sectional side view of the overall structure of the copier using the process cartridge of the present invention. An image reading device 3 is installed on the top of the body casing 2 of the copier 1 for reading images of original documents (not shown). A process cartridge 4 is detachably provided inside the casing 2, and a paper transport path 6 is formed below the process cartridge 4 for transporting transfer paper 5 as a recording medium.

[0043]The image reading device 3 includes an image reading unit 7 and a document tray 8. The image reading unit 7 feeds a document placed on the document tray 8 to a reading position for reading. As the center, it turns between the horizontal position represented by the solid line and the standing position represented by the double-dashed line, and the positions are fixed by th...

Abstract

The invention relates to a process cartridge, a manufacturing method of the cartridge, and an image forming apparatus. The photoreceptor assembly (10) and the developing assembly (11) are connected in such a way that the side plates of the photoreceptor assembly (10) and the developing assembly (11) The parts (10a, 11a) are in surface contact, so that the pin insertion holes (40, 46) respectively formed on the side plate parts (10a, 11a) overlap, and the connecting pins are pressed into the above-mentioned pin insertion holes, and one side plate part The fitting protrusion (47) on (11a) is elastically fitted into the fitting hole (41) on the other side plate portion (10a). The photoreceptor assembly (10) and the developing assembly (11) are connected by an inexpensive structure without increasing the number of parts such as connecting plates, and the work can be performed simply without using jigs and the like.

Description

technical field [0001] The present invention relates to a process cartridge formed by connecting a photoreceptor unit and a developing unit in which a photoreceptor drum is rotatably mounted, a method for manufacturing the process cartridge, and an image forming apparatus. Install the developing roller. Background technique [0002] Conventionally, in image forming apparatuses such as copiers and printers, a process cartridge is generally provided, that is, a photosensitive drum and a developing roller are mounted in a casing, and the photosensitive drum and the developing roller are replaced simultaneously in units of casings. [0003] In this kind of process cartridge, in order to improve the assembly, some process cartridges are assembled separately with a photoreceptor unit on which a photoreceptor drum is rotatably installed and a developing unit on which a developing roller is rotatably installed. It is formed by connecting the above-mentioned photoreceptor assembly a...
