Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

First, as shown in fig. 1 to 4, there is a conventional process cartridge B and image forming apparatus, an apparatus main body a of which includes an openable cover 101, a cartridge pressing member 106, a cartridge pressing spring 105, a driving part 104, an upper rail 102, a lower rail 103. The process cartridge B is mounted into the image forming apparatus by the guidance of the upper rail 102 and the lower rail 103, and by the closing of the cover 101, a cartridge pressing member 106 attached to the cover falls between the process cartridge B and a cartridge pressing spring 105, and the cartridge pressing spring 105 urges the process cartridge B by the cartridge pressing member 106 so that the process cartridge B comes into contact with a cartridge positioning portion (not shown in the drawings) in the image forming apparatus to position the process cartridge B in the image forming apparatus. The driving member 104 is for driving a rotating member such as a photosensitive drum in the process cartridge to rotate.

As shown in fig. 4 and 5, the conventional process cartridge B includes a casing 1, a photosensitive drum 2, a developing roller 3, a handle 6, a drum driving part 7, a developing roller driving part 8, a chip 4, and a chip holder 5. Wherein, in the longitudinal direction of the process cartridge, the conductive end of the casing 1 where the chip 4 is located and the driving end of the casing 1 where the drum driving part 7 and the developing roller driving part 8 are located are opposite sides. In this prior art, the chip 4 is attached to the chip holder 5 by means of glue, and the chip holder 5 is also difficult to detach from the process cartridge. Since the process cartridge in the related art is given to the end user along with the image forming apparatus when the image forming apparatus is first sold, the end user needs to purchase a new process cartridge to replace it when the end user comes to the end of the life of the process cartridge. However, the chip 4 in the process cartridge whose life is ended at this time is not disabled by the reception of the life of the process cartridge, but can continue to be replaced in a new process cartridge to continue the operation. On the other hand, the chip is used as a component for information communication between the processing box and the imaging device, and the processing box is not recognized by the imaging device without the chip, so that the chip on the old processing box needs to be detached and installed on a new processing box for recycling in order to protect the environment and reduce the manufacturing cost of the processing box and the use cost of a user.
