[0075] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0076] figure 1The outline of the image forming apparatus 10 according to the embodiment of the present invention is shown. The image forming apparatus 10 includes an image forming apparatus body 12 . An image forming device 14 is installed in this image forming apparatus main body 12 . The delivery unit 16 is installed on top of the image forming apparatus main body 12 . A sheet feeder 18 is installed at a lower portion of the image forming apparatus main body 12 .

[0077] The delivery portion 16 has an inclined portion 22 that is rotatable around the image forming apparatus body 12 . The inclined portion 22 whose output side is located at a low place gradually rises toward the front ( figure 1 center to the right). The inclined portion 22 has the output side as its bottom end and the raised front end as its top end. The inclined portion 22 i...

[0162] An imaging cartridge, and its assembly and disassembly method, including the structure in the first embodiment, in Figure 1 to Figure 3 0 has been explained. Therefore, details are not described in this embodiment.

[0163] Figure 31 It is a cross-sectional view showing the overall components of the joint part of the imaging cartridge 40, wherein the first case 37 and the second case 39 are combined through the connecting pin 56 in the embodiment. Figure 31 It shows that the first casing 37 and the second casing 39 are combined with each other by means of the connecting pin 56 so that a part of the second casing 39 is inserted between the two parts of the first casing 37 from both sides. The second insertion hole 55 of the second case 39 is arranged between the first insertion holes 54A and 54B of the first case 37 . In this case, the first insertion holes 54A and 54B, and the second insertion hole 55 have the same inner diameter W1.

[0164] The connection pin 5...

Abstract

A process cartridge includes an image carrier, a developing device, a first casing for supporting the image carrier, and a second casing for supporting the developing device. The first casing and the second casing are freely combined in a rotatable manner as coupling pins are inserted into first insertion holes formed in the first casing and a second insertion hole formed in the second casing. An engaging means, by which the coupling pin is press-fit into the first insertion hole, and the coupling pin is kept from being press-fit into the first casing and the second casing after being pre-fit, is disposed in at least one of the first casing and the second casing, and the coupling pin.

Description

technical field [0001] The present invention relates to an image forming cartridge for use in an image forming apparatus such as a printer, copier or facsimile, and to an assembly method and a disassembly method thereof. Background technique [0002] Traditionally, an image forming apparatus using electrophotography has adopted an imaging cartridge in which an electrophotographic photoreceptor (image carrier), an imaging device acting on the electrophotographic photoreceptor, and a A detachable cartridge on an image forming device. [0003] In such an image forming cartridge, a first housing for supporting at least an electrophotographic photoreceptor, and a second housing for supporting at least a developing device are rotatably connected together by connecting pins. At this time, in order to prevent the connecting pin from being disengaged from the first casing and the second casing, the connecting pin is press-fitted into at least one of the first casing and the second c...
